Question

A rectangle has an area of 115m2.

One of the sides is 5m in length.
Work out the perimeter of the rectangle.

Answer 1

56m

Explanation:

Answer 2

Since the formula of a rectangle is length*width and we know the length of one side is 5m then we can do the opposite of multiplying and divide 115 by 5 to get the length of the other side (23m).

The formula for a rectangles perimeter is all the side lengths added together. Therefore 5 + 5 + 23 + 23 = 56m
