Question

If you have a square with a perimeter of 18 inches, what is the area of the square after

scaling it by 7? Round to the nearest tenth is needed.

Answer 1

992.3 in^2 to the nearest tenth.

Explanation:

The new perimeter will be 7*18 = 126 inches.

So the side of the new square will be 126/4 = 31.5 inches,

and it's area = 31,5^2

= 992.25
