Step 1) Split the figure into separate shapes
Triangle: 6 x 11
Small square: 2 x 2
Large rectangle (center): 16 x 7
Medium rectangle (bottom): 2 x 5
Step 2) Find the area of each shape
Triangle: A = 6 x 11 x 1/2 = 33
Small square: A = 2 x 2 = 4
Large rectangle (center): A = 16 x 7 = 112
Medium rectangle (bottom): A = 2 x 5 = 10
Step 3) Add the areas together
A = 33 + 4 + 112 + 10 = 159 square meters
Hope this helps! :)
