Question 943235
There is no diagram,so no wall is shown.
But a trapezoid with bases 11 ft and 14 feet and height of 9 feet has area:
{{{total area=((11ft+14ft)/2)(9ft)}}}=112.5 sq ft
area of door=(7.5)(2.5)=18.75 sq ft
area to paint=total area-area of door
area to paint=112.5 sq ft-18.75 sq ft
area to paint= 93.75 sq ft
The area of a trapezoid with bases 11 ft and 14 ft and height 9ft less the area of a door 2.5 ft by 7.5 ft is 93.75 feet.
