Answer:
37 m^2
Step-by-step explanation:
The shape can be broken down into a rectangle (on the top), two triangles (at the side) and another big rectangle (centre)
Area of one triangle
= 1/2*base*height
= 1/2*4*1
=2 m^2
Area of 2 triangles= 4m^2
Area of the small rectangle
= Length*breadth
= 1*3
= 3 m^2
Area of large rectangle in the same way
= 4*8
= 32m^2
Total area
= Sum of all the sub-areas
= 32+3+2
=37 meters^2
