The perimeter of the rectangle is 2,500 cm. Find the unknown side length. the other side is 750
sineoko [7]

Answer:

<h2>500 cm</h2>

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

<h3>500 cm</h3>

Hope this helps you
