The shape will be divided into two rectangles.
Area of rectangle = length * width
Ist rectangle:
Length = 13 in
width = 4 in
Area of 1st triangle = 13 × 4 = 52 in²
2nd rectangle:
length = 15 in
width = 10 in
Area of 2nd rectangle = 15 × 10 = 150 in²
Area of the shape = area of 1st rectangle + area of 2nd rectangle
Area of the shape = 52 + 150
Area of the shape = 202 in²
