Question

Please help and explain!

Answer 1

First you find the square and the are of the square would be 7*4=28.

then you move on to the triangles the purple ones together are 7 * 5 = 35 , since there’s 2 you don’t have to divide the area by 2 just use it as the combined for both

then black same thing 4*3 = 12

so
12+35+28=75
