Question

Rectangle swim pool was 9 meters wide with surface area of 90 square meters. What's length of the pool?

Answer 1

90/9 = 10, the length of the pool.  This can be proven as 10 x 9 = 90²

Answer 2

Explanation:

alright, lets get started.

The area of the rectangle is given by the formula :
`length*width`

Suppose the length of the pool is l

area is given as 90 and width is given as 9

Plugging the values in formula:

`90=9*l`

Dividing 9 in both sides

`l=(90)/(9)=10`

So, the length of the pool is 10 meters. : answer
