Problem
A square and a triangle have equal perimeters. The lengths of the three sides of the triangle are , and . The area of the square is
Solution
We are given the three side lengths of the triangle, so we can compute the perimeter of the triangle to be . The square has the same perimeter as the triangle, so its side length is . Finally, the area of the square is , which is choice
