What is the area of this composite shape?

Total area = 51 in²

Step-by-step explanation:

Section the shape into a rectangle and a triangle.

Area of a rectangle = width x length

⇒ area = 6 x 7 = 42 in²

Area of a triangle = 1/2 x base x height

⇒ area = 1/2 x (6 - 3) x (13 - 7) = 9 in²

Total area of composite shape = 42 + 9 = 51 in²
