Question

What is the area of this composite shape?

Answer 1

51

Explanation:

6 * 7 = 42

the side of the triangle can be found by subtracting 7 for 13, which is 6

so

6 * 3 = 18

since it's a triangle and the fomula is 1/2BH we're going to divide 18/2 to get 9

42 + 9 = 51

I took the test and this was the correct answer :^D

Answer 2

S = S1 + S2 = 6*7 + 1/2*3*6 = 42 + 9 = 51
