If he swan the length and the width of the pool  it would be 21 x28 = 588 sq ft.
by swimming the length and the diagonal of the pool (25 ft)  found that by using the pythagorean therom      so now you are multiplying 21 x 25 = 525   

588-525= 63 ft   he is saving

Two consecutive perfect squares have a difference of $99$. what is the value of the larger perfect square?
Fofino [41]

Answer:

2500

Step-by-step explanation:

Let the first square number be x^2 then the next square number is (x+1)^2.

The difference between these two consecutive numbers is 99.

This implies that:

(x+1)^2-x^2=99

We expand to get:

x^2+2x+1-x^2=99

Simplify:

2x=99-1

2x=98

Divide both sides by 2

x=49

Therefore the value of the larger perfect number is

(49+1)^2=50^2=2500.
