Answer:
44 in²
Step-by-step explanation:
The figure is composed of a triangle, a rectangle and a trapezium.
Area of the triangle =  bh =
 bh =  × 3 × 4 = 6 in²
 × 3 × 4 = 6 in²
Area of the rectangle = lb = 10 × 3 = 30 in²
Area of trapezium =  h (a + b)
 h (a + b)
where h is the height and a, b the parallel bases, thus
area of trapezium =  × 2 × (5 + 3) = 1 × 8 = 8 in²
 × 2 × (5 + 3) = 1 × 8 = 8 in²
Total area = 6 in² + 30 in² + 8 in² = 44 in²
