Question

the above question answer​

Answer 1

Answer:

Step-by-step explanation:

Here BDC and ABD are triangles such that ar (BDC)+ar(ABD)=ar (ABCD)

So

area of BDC=1/2×base×height

=1/2×60×13

=30×13

=390m^2

Now,

area of ABD=1/2×base×height

=1/2×40×9

=20×9

=180m^2

ar (ABCD)=ar(BDC) + ar(ABD)

=390+180

=570m^2
