Question

Shane plans to paint his barn he will paint the rectangular sides including the door and the 2 triangular sections formed by the roof Calculate the number of square feet of surface area that Shane will paint

Answer 1

3164

Step-by-step explanation:

The area of the house to be painted equals

Area of the rectangular sections + Area of triangular sections

Now,

Area of the rectangular sections = front + back + sides

front = 24 * 20 = 480

back = 24 * 20 = 480

sides = 20 * 45. 5 + 20* 45. 5 = 1820

Therefore,

total area of the rectangular sections = 2780

and,

Area of triangular sections = (28-20)* 24 + (28-20)* 24 = 384

Therefore,

Area to be painted = Area of the rectangular sections + Area of triangular sections = 2780 + 384 = 3164

Hence,

Area to be painted = 3164

which is our answer!
