Think of the shape as being made up of a rectangle on the left side and a triangle on the right side. Find the two areas and add them.
The left side is a rectangle 40 units by 48 units.
The right side is a triangle with base 48 units and height 16 units.
total area = area of rectangle + area of triangle
total area = LW + bh/w
total area = 40 * 48 + 48 * 16/2
total area = 1920 + 384
total area = 2304 units^2
Answer: c. 2304 units^2
