Answer:

96 units

Step-by-step explanation:

You have to split it into parts then add all together. 3 x 7 equals 21   4 x 7 equals 28 and 5 x 7 equals 35. 4 x 3 equals 12. But you have to split that in half for the area of a triangle. So, 21 + 28 + 35 + 6 + 6 = 96

96 units space you have to spray and divide all the units
