Question

7. The perimeter of a rectangular pool is 70 meters. If the width of the pool

is 12 meters, then find its length.

Answer 1

P of rectangle = 2 length + 2 width

> 70 = 2length + 24
Subtract 24 from both sides
> 46 = 2length
Divide by 2
> 23= length

The length of the pool is 23 meters

Answer 2

23 meters

Explanation:

You would subtract 24 from 70, and then divide by two.

70-24=46

46/2 = 23
