Question

a rectangle swimming pool was 9 meters wide with a surface area of 90 square meters. what is the length of the pool​

Answer 1

Answer:

area = l*b

given area = 90m^2

b=9m

:. l = 90/9 =10m

Answer 2

Given:

• Length of Rectangle pool = 10 m
• Perimeter of Rectangle pool = 38 m.

Step By Step Explanation:

Given:

• Area of Rectangle = 90 m²
• Breadth of Rectangle = 9 m

To Find:

• Length of Rectangle pool.

Now, we know that,

=> Area of Rectangle = length × breadth

=> 90 = length × 9

=> length = 90/9

=> length = 10 m.

Hence, Length of pool = 10 m.

Extra Information:

Now, we will calculate perimeter of Rectangle pool,

=> Perimeter of pool = 2(length + breadth)

=> Perimeter of pool = 2(10 + 9)

=> Perimeter of pool = 2(19)

=> Perimeter of pool = 38 m.

Hence, perimeter of pool = 38 m.
