Answer:

Pete will need 72 square inches of wood

Explanations:

The area of a square = Length²

The area of a rectangle = 1/2 x base x height

The area of the doll house = The area of the roof + The area of the walls

The roof is triangular in shape

height = 4 inches

base = 4 inches

Area = 1/2 x 4 x 4

Area of the roof = 8 in²

Area of the wall = l²

Area of the wall = 8²

Area of the wall = 64 in²

Area of the doll house = 8 + 64

Area of the doll house = 72 in²

Pete will need 72 square inches of wood
