Question

I asked this already, but can somebody provide an answer with an explanation?

Answer 1

Concepts:

• Finding area
• Area of figures

Answer: 41 cm²

Triangle lengths:

A(ABN) = 1/2b₁h

A(CDM)= 1/2b₂h

Trapezoid length:

A(ABCD) = 1/2(b₁ + b₂)h

A = 23 + 18 = 41 cm²

Answer 2

• 41 cm²

Explanation:

Area of triangles

• A(ABN) = 1/2b₁h
• A(CDM)= 1/2b₂h

Area of trapezoid

• A(ABCD) = 1/2(b₁ + b₂)h

Since the area of trapezoid is same as the sum of the areas of the triangles, we have:

• A = 23 + 18 = 41 cm²
