Answer 2

Answer:

1,728m²

Step-by-step explanation:

1. ΔBEO

B=24 m, H = 48m

⇒1/2×24m×48m=576m²

2. ΔBDO

B=12m,H=84m

⇒1/2×12m×84m=504m²

3.Treapezium

b1=12m and b2=6m, h=6m

⇒1/2×(12m+6m)×6m

⇒1/2×18m×6m=54m²

4.ΔAOC

B=6m,H=6m

⇒1/2×6m×6m=18m²

5.ΔEOA

b=24m,h=48m

⇒1/2×24m×48m=576m²

Area of field = ΔBEO+ΔBDO+TRAPEZIUM+ΔAOC+ΔEOA

⇒576M²+504M²+54M²+18M²+576M²

⇒1,728M² Ans.

⇒ Hence, the area of the field is 1,728m².
