Question

the ratio of the side lengths of a square is 3:5. Square B's perimeter is 60 ft. What is the area of Square B? ANSWER

Answer 1

You did not identify the ratio of a sides as that of square A to square B, specifically.

 

If that is the meaning of the given 3:5 ratio, then the area of square A is (3/5)²  of that of square B. (And of course, the area of square B is 15 by 15 sq units)

But it appears to me that the question ought to have been asking for the area of square A--otherwise what is the puyrpose of the mention of ratios>

Answer 2

60/4 = 15 (side length in square b)

 

area = length * width 

 

area = 15 * 15 = 225 ft²
