Explanation: The area of a square is 36, there are five squares which equals 180. Then you have to add the area of the four triangles, which one triangle has the area of 18. Which equals 72 for all the triangles. If you add 180 and 72 it equals 252
Total area of the wall = 28 * 12 = 336 ft²
time = 5 1/4 = 21/4 hours
speed = 336 / 21/4 = 64 ft²/hour
