Answer:
366 cm²
Step-by-step explanation:
Finding the area of an irregular figure is the sum of the area of all the figures. In this diagram, there is a rectangle and a triangle. The formulas for the area of these figures is:
A(rectangle) = length x width
A(triangle) = 1/2 base x height
Using the dimensions in the figure:
A(rectangle) = 14 x 21 = 294 cm²
A(triangle) = 1/2 (16) x (21 - 12) = 8 x 9 = 72 cm²
Total Area = 294 + 72 = 366 cm²
