The correct option is B 240 sq in
The composite figure consists of one triangle and one rectangle.
Area of triangle = 12 × base × height
Base of triangle = 20 in
Height of triangle = 4 in
Area = 12 ×20 × 4
= 40 sq in
Area of rectangle = base × width
Base of the rectangle =20 in
Height of the rectangle = 10 in
Area = 20 × 10 = 200 sq in
Hence, area of the composite figure = 40 + 200 = 240 sq in
