Answer:
The area of the figure is 286 cm^2
Area of upper triangle = (1/2) base X height
= (1/2) 12 X 10
= 60
The middle portion is square so
area = l^2
= 100
the base of bottom triangle = 4 + 10 + 4 = 18
height of bottom triangle = 14
so area = (1/2) base X height
= 126
total area = area of upper triangle + area of square +area of bottom triangle
= 60 + 100 + 126
= 286 cm^2
