Answer:

44 in²

Step-by-step explanation:

The figure is composed of a triangle, a rectangle and a trapezium.

Area of the triangle = $\frac{1}{2}$ bh = $\frac{1}{2}$ × 3 × 4 = 6 in²

Area of the rectangle = lb = 10 × 3 = 30 in²

Area of trapezium = $\frac{1}{2}$ h (a + b)

where h is the height and a, b the parallel bases, thus

area of trapezium = $\frac{1}{2}$ × 2 × (5 + 3) = 1 × 8 = 8 in²

Total area = 6 in² + 30 in² + 8 in² = 44 in²
