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
