Question

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

Answer 1

Answer:

500 cm

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

where

l is the length

w is the width

From the question we have

$2500 = 2l + 2(750) \\ 2500 = 2l + 1500 \\ 2l = 2500 - 1500 \\ 2l = 1000 \\ \frac{2l}{2} = \frac{1000}{2} \\ l = \frac{1000}{2} \\ l = 500$

We have the final answer as

500 cm

Hope this helps you
