Answer: 64 square inches (choice B)
========================================================
Step-by-step explanation:
Split the house shaped figure into a triangle on top and a rectangle down below.
The rectangle has area of length*width = 8*6 = 48 square inches. The 6 is from 10-4 = 6.
The triangle has area of base*height/2 = 8*4/2 = 32/2 = 16
Overall, the total area is 48+16 = 64 square inches
