Answer:
300 m^2
Step-by-step explanation:
Quad. ABDE is an Rectangle.
Ar (ABDE) = l x b
=> Ar ( ABDE) = ( 20 x 12 ) m^2
=> Ar (ABDE) = 240 m^2 ...(1)
Ar (DEC) = 1/2 x base x height
=> Ar (DEC) = 1/2 x EC x DE
=> Ar (DEC) = ( 1/2 x 10 x 12 ) m^2
=> Ar (DEC) = 60 m^2 ...(2)
Ar (ABCD) = AR(ABDE + DEC)
=> AR (ABCD) = (240+60) m^2 = 300 m^2
I hope you liked the answer. If it helps make sure to mark it as brainliest if possible.
Happy preparation!
Have a nice day ahead ;)
