Sagot :

The area of the polygon is the sum of the area of rectangle + area of triangle = 316 cm². (Option C)

Area of Polygon

The polygon is composed of a triangle and a rectangle.

Area of the polygon = Area of Triangle + Area of Rectangle

Area of Rectangle = length × width

Length = 21 cm

Width = 14 cm

Area of rectangle = 21 × 14 = 294 cm²

Area of Triangle = 1/2(base × height)

Base = 21 - 10 = 11 cm

Height = 18 - 14 = 4 cm

Area = 1/2(11 × 4) = 22 cm²

Therefore:

Area of Polygon = 294 + 22 = 316 cm².
