Answer:
400 in²
Step-by-step explanation:
The figure is composed of a parallelogram and a triangle
The area of the parallelogram is calculated as
area = bh ( b is the base and h the perpendicular height )
Here b = 20 and h = 16, thus
area = 20 × 16 = 320 in²
The area of the triangle is calculated as
area = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here b = 20 ( opposite sides of a parallelogram are congruent ), h = 8
area = [tex]\frac{1}{2}[/tex] × 20 × 8 = 10 × 8 = 80 in²
Area of figure = 320 + 80 = 400 in²
