Question

find the area of polygon​

Answer 1

Answer:

21,735 cm².

Step-by-step explanation:

Area of the biggest triangle = 120 * 76 * ½ = 4560.

Area of another triangle = 90 * 95 * ½ = 4275.

Area of another triangle = 100 * 125 * ½ = 6250.

Area of the last triangle = 76 * 100 * ½ = 3800.

Area of the trapezium = area of rect - area of triangle = (125 * 30) - (30 * 30) = 2850.

Total area of figure = 4560 + 4275 + 6250 + 3800 + 2850 = 21,735 cm².
