hope this helps!

81 m^2

Step-by-step explanation:

First find the area of the lower rectangle

A = l*w

A = 12* 5 = 60m^2

Then we find the area of the middle rectangle

The height is 4m - 3m = 1 meter

The length is 12m - 3m = 9m

A = 9*1 = 9m^2

Then we find the area of the top rectangle

The length is 4 m and the width is 3 m

A = 3*4 = 12m^2

The total area is 60+9+12 =81 m^2
