Help me now please ive been in this question for a really long time

Step-by-step explanation:

Since we are given the perimeter and the triangle sides we can find the length of the three sides of the square

2(20)+3s=112

3s=72

The total length of the three sides is 72 inches with each side equal to 72/3=24 inches.

The area of the triangles is hb/2 where the base is equal to the side of the square and a height of 16.

The area of the triangle is 24(16)/2=192in^2 and the area of the square is 24(24)=576in^2

And the total area is 192+576=768in^2.
