Question

Answer 1

When finding the area of a composite shape, save yourself some calculation time by bundling identical shapes. The roof triangle parts make one rectangle 2 by 4.5 so that area is 9. Add to this the area of the house bottom of 3 times 9 or 27 and get a total of 36 square inches.

Answer 2

Answer - B. 36in²

step 1. find the area of the rectangle by multiplying the length times the width

3*9 = 27in²

step 2. find the area of the triangles

the dotted line perpendicular to the base means that there are 2 right triangles

the formula to find the area of a right triangle is (1/2)*b*h

2*4.5*(1/2) = 4.5in²

2*4.5*(1/2) = 4.5in²

step 3. add all the total areas

4.5 + 4.5 + 27 = 36in²
