Answer:

  • 41 cm²

Step-by-step 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

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
