Answer:
174 feet squared
Explanation:
The figure is composed of a rectangle and a right triangle
Therefore,
Area of the composite figure = area of the rectangle + area of the right triangle
= (L*W) + (½*b*h)
L = 18 ft
W = 9 ft
b = 18 - (6 + 6) = 6 ft
h = 4 ft
Plug in the values into the equation
Area of the composite figure = (18*9) + (½*6*4)
= 162 + 12
= 174 ft²
