a rectangle swimming pool is 4 ft deep. one side of the pool is 2.5 times longer than the other. the amount of water needed to f
mojhsa [17]

Find the are of the pool by dividing the volume by the depth:

1960 / 4 = 490

The pool is 490 square feet.


Area is found by multiplying the length by the width.

Let the width = X

We are told the length is 2.5X ( 2.5 times longer)


So we now have 2.5x * x = 490


2.5x * x = 2.5x^2


Now we have 2.5x^2 = 490


Divide both sides by 2.5:

x^2 = 490/2.5

x^2 = 196

find X by taking the square root of 196:

x = √196

x = 14


The width is 14 feet

The length is 2.5 * 14 = 35 feet

Arisa [49]

Answer:

71

Step-by-step explanation:

Area of fig 1 = 1 x b = 7 x 4 = 28

Area of fig 2 = l x b = (7-2) x 3 = 5 x 3 = 15

Area of fig 1 = 1 x b = 7 x 4 = 28 (same as ig 1)

Area of whole fig = fig 1 + fig 2 + fig 3 = 28+15+28 = 71

I hope im right !!
