Question

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

Answer 1

Answer:

Step-by-step 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

$l=\frac{90}{9}=10$

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

Hope it will help :)

Answer 2

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