Answer:
135 ft²
Step-by-step explanation:
The profile is composed of a triangle and a rectangle.
Area of profile = (area of triangle) + (area of rectangle)
= (½×base×height) + (length × width)
Where,
base of triangle = 15 ft
height of triangle = 11 - 7 = 4 ft
length of rectangle = 15 ft
width of rectangle = 7 ft
Plug in the values
Area of profile = = (½×15×4) + (15×7)
= 30 + 105
Area of profile = 135 ft²
