Answer:
4 ft²
Explanation:
A = 1/2bh Use this equation to find the area of the triangle
A = 1/2(4)(4) Multiply
A = 1/2(16) Multiply
A = 8 Area of entire triangle
A = 1/2(2)(4) Multiply
A = 1/2(8) Multiply
A = 4 Area of triangle not shaded
Take the area of the whole triangle minus the area of the unshaded part
8 - 4 = 4 ft²
