Answer 2

Answer:

The area of the square pool is 144 sq .cm.

Step-by-step explanation:

Given : Around a square pool,there is a footpath of width 2m. If the area of the footpath is 7/9 times that of pool

To find : The area of pool?

Solution :

Let the length of the pool is x

According to question,

(x - 12)(7x + 12) = 0

(x - 12)=0 or 7x + 12)=0

x = 12  or x =- 12/7

BUT,

x =- 12/7 is not acceptable

Therefore, The length of the pool is x = 12  m

The area of the square pool is

A=12 × 12=144 centimeter²

Therefore, The area of the square pool is 144 sq .cm.
