Answer: the area of the fabric he will have leftover is 140 inches²
Step-by-step explanation:
The formula for determining the area of a triangle is expressed as
Area = 1/2 × base × height
From the given information,
Height = 2 inches
Base = 4 inches
Area of triangle = 1/2 × 4 × 2 = 4 inches²
The formula for determining the area of a square is expressed as
Area = length ²
Length = 12 inches
Area of square = 12 × 12 = 144 inches²
The area of the fabric he will have leftover is area of square - area of triangle. It becomes
144 - 4 = 140 inches²
