Answer:
B) 180 ft. squared
Step-by-step explanation:
Multiply all sides of the figure by 3 because of the scale factor
6 times 12 = 72 (for the rectangular part)
6 times 6/2 = 18 (for the triangular part)
We know that the base and height of the triangle are congruent because of the tic marks
18 + 72 = 90
Multiply by 2 since that is only half of the side of the house
90 times 2 = 180
