The area of the irregular polygon in the sketch is: D. 40.5 cm².
To find the area of an irregular polygon, decompose the polygon into known shapes. Find the area of each shape and add all together.
Thus:
The irregular polygon is made up of a rectangle and a triangle.
Area of the irregular polygon = area of rectangle + area of triangle.
= length × width + 1/2(base × height)
Length = 12.5 cm
Width = 3 cm
Base = 3 cm
Height = 2 cm
Area of the irregular polygon = 12.5 × 3 + 1/2(3 × 2)
= 40.5 cm²
