So, it will give the coverage of the rectangle as a two-dimensional plane. Area: Area of the rectangle describes the amount of space covered by it.Perimeter: It is the sum total of all four sides of the rectangle.Diagonal: It is the direct straight line distance between two opposite vertices of the rectangle.Breadth: It is the smaller side of the rectangle.Length: It is the longer side of the rectangle.Some terms related to this shape are as follows: Some measurement in rectangle as Perimeter, Diagonal, Area, etc. We have to perform a various measurements to complete some important tasks. When the four sides of a rectangle are made equal, then it is called a square. A rectangle is a parallelogram with right angles in it. A rectangle is also called an equiangular quadrilateral, as all the angles of a rectangle are right-angled. To recall, a rectangle is a four-sided polygon and the length of the opposite sides is equal. Most likely, the room in which we are sitting in some form of a rectangle or a combination of rectangles. If we look around us, then we can see many examples.

90-degree angles and with equal length of opposite sides. A rectangle is any four-sided figure with four right angles i.e. Thus rectangle is a very common shape in our daily life. Or, we may wish to do fencing of the playground in a rectangular shape. For example, suppose we are looking to sod our lawn, then we would need to know the area of our lawn in order to implant grass in it. There are many authentic and real-life purposes where we would need to calculate some measurements of various shapes. Let’s start learning! Rectangle Formula What is a Rectangle? In this article, we will discuss rectangles, some related terms and definitions and also rectangle formula with examples. Some objects of this type of shape are playground, an A4 sheet of paper, room wall, etc. Decompose a parallelogram into two congruent triangles, and compare the area of one of the triangles with the area of the parallelogram.We may have come across many objects in our daily life which is rectangular in shape.Decompose a rectangle and rearrange the parts to compose a parallelogram with the same area.Create two different triangles with an area of 12 square units, using a geoboard.Estimate and calculate the area of composite two-dimensional shapes by decomposing into shapes with known area relationships.Construct three similar rectangles, using grid paper or a geoboard, and compare the perimeters and areas of the rectangles.The area of a parallelogram is the exact same as the area of a rectangle, which is length x width (or base x height). The reason for that is that is if I cut the end piece of the parallelogram, I can slide it to the opposite side and create a rectangle. Finding the area of parallelograms is easy, all you have to do is multiply the base by the height. If you look at the picture below each of the triangles is only half of the size of a rectangle, which is why the formula is 1/2 x b x h. The reason for that is that is if I go base x height (or length x width) that is the same formula as the area of a rectangle. Finding the area of triangles is easy, all you have to do is multiply the base by the height and half the answer. If each row has 18 squares, if we have 6 rows, we would then go 6 x 18 which is 108 squares in total. An array means using rows and then adding it all up. Another way of finding the area of a rectangle is using an array. Finding the area of rectangles is easy, all you have to do is multiply the length by the width. Rectangles, Triangles and Parallelograms Design and construct different rectangles, given either perimeter or area, or both (whole numbers), and make generalizations.constructing different rectangles for a given area (cm2 or m2) in order to demonstrate that many different rectangles may have the same area.using area formulas for rectangles and triangles to solve problems involving areas of surfaces.establishing that the area of a triangle is half the area of an appropriate rectangle.building on the understanding of the area of rectangles to develop formulas for the area of triangles.I can find and use the formula for the area of rectangles, triangles and parallelogram to solve problems involving the areas of surfaces.That formulas can be used to quickly find the area of a rectangle, triangle or parallelogram.the properties of rectangles, triangles and parallelograms.the dimensions of 2-D shapes such as length and width (height).LO: To find the formula for the area of rectangles, triangles and parallelograms. Establish the formulas for areas of rectangles, triangles and parallelograms and use these in problem solving (VCMMG258)
