Question

The perimeter of the rectangle is 2,500 cm. Find the unknown side length. the other side is 750

Answer 1

500 cm

Explanation:

Perimeter of a rectangle = 2l + 2w

where

l is the length

w is the width

From the question we have

`2500 = 2l + 2(750) \\ 2500 = 2l + 1500 \\ 2l = 2500 - 1500 \\ 2l = 1000 \\ (2l)/(2) = (1000)/(2) \\ l = (1000)/(2) \\ l = 500`

We have the final answer as

500 cm

Hope this helps you
