Think of the area divided into two parts.
A rectangle, 4.8 units by 9.6 units,
and a triangle with base 9.6 units and height 9 - 4.8 = 4.2 units.
Find the areas of the rectangle and triangle and add them.
Rectangle:
A = LW = 4.8 * 9.6 = 46.08
Triangle:
A = bh/2 = 9.6 * 4.2/2 = 20.16
Add the areas:
46.08 + 20.16 = 66.24
Answer: d. 66.2 units^2
