Question

Perimeter 94 cm and length 39. What’s the width

Answer 1

Hello.

To find the perimeter of a rectangle, use the formula P = 2(l + w).

Input 39 as l.

94 = 39 + 39 + w + w

Simplify

94 = 78 + 2w

Subtract the two known numbers

94 - 78 = 16

16 = 2w

So that means w = 8.

The width is 8.

Answer 2

8

Explanation:

Take the length and multiply it by 2. then take your answer and multiply it by the perimeter. Then, take that answer and divide it by 2. Hope this helps :)
