Question

how to find the area of polygon​

Answer 1

Break it into smaller shapes

Triangle and Trapezium

Triangle = 1/2 * b * h

Triangle = 1/2 * 6 * 8

Triangle = 24 cm^2

Trapezium = a+b/2 * h

(h = 13 - 8 = 5)

Trapezium = 6+12/2 * 5

Trapezium = 9 * 5

Trapezium = 45 cm^2

Total area = 24 + 45

Totl area = 69 cm^2
