The side of a square is 5 cm more than the side of another square. If the sum of their areas is 625 cm², then the side of the bigger square is

Let the length of each side of the smaller square be . Then area of the square is .

The length of each side of the larger square will be .

Then the area of the square will be

As per the question the area of the larger square is four times the square of the smaller square.

Therefore

We get , and

Considering the positive value we get

Therefore the side of the squares are cms and cm.

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
