If we slice this down the middle and fit it together like a puzzle we'll get a rectangle base 9.6/2 and height 4.8+9 so area (9.6/2)(4.8+9) = 66.24 square units.

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
