Whats the area?

PLEASE HELP

The perimeter is given as 112.

The two lines at the top Are 20 each, so subtract 40 from 112 for the length of the 3 sides:

112 - 40 = 72 inches

The length of one side would be 72/3= 24 inches

Area of the triangle is 1/2 x base x height = 1/2 x 24 x 16 = 192 square inches.

Area of square is S^2 = 24^2 = 576 square inches.

Total area = 192 + 576 = 768 square inches.
