#FINDING THE AREA OF A RECTANGLE HOW TO#

The units are in place to give an indication of the order of the calculated results such as ft, ft 2 or ft 3. I measure a rectangle with my ruler, and find L 10 +/- 1 cm and w 5 +/- 1 cm. Note: Sometimes, base and height are used instead of length and width. The area, A, of a rectangle is the product of its length, l, and width, w. Examples of square units of measure are square inches, square centimeters, or square miles.

Let’s write an equation that sets the perimeter of the rectangle and the square equal. We also know that if s is the length of a side of a square, then the perimeter is 4 s, because each side of the square is congruent. The grey space is the area of the rectangle in the diagram below. You measure area in square units of a fixed size. The perimeter of a rectangle is given by 2 l + 2 w.

It also explains how to calculate the area of composite. where A is the area, L is the length, W is the width. This geometry video tutorial provides a basic introduction into calculating the area of a rectangle. Units: Note that units of length are shown for convenience. /rebates/2fssatelementarylevelmath-help2fhow-to-find-the-area-of-a-rectangle&. The area of a rectangle is the space contained within its perimeter. To find the area of a rectangle, multiply the length by the width. Solved examples to find the area of a rectangle when length and breadth are given. Use this calculator if you know 2 values for the rectangle, including 1 side length, along with area, perimeter or diagonals and you can calculate the other 3 rectangle variables.Ī square calculator is a special case of the rectangle where the lengths of a and b are equal. So when we multiply its length and breadth we get the area of the rectangle.
