Question

The doghouse shown has a floor, but no windows. Find the total surface area of the doghouse (including the door).

Answer 1

= 236 ft^2.

Explanation:

Area = area of the 4 rectangular walls + 2 * triangular wall + 2 rectangular parts of the roof + area of the floor

= 2*6*4 + 2*7*4 + 2*1/2*5*4 + 2*5*7 + 7*6

= 48 + 56 + 20 + 70 + 42

= 236 ft^2.
