answer:
63 inches squared
step-by-step explanation:
- in order to find the area of just the shaded portion, we would have to subtract the not shaded portion from the whole rectangle
- first, find the area of the whole rectangle
1 ft = 12 inches (conversion)
12 X 6 = 72 in^2 (area of the whole rectangle)
- now, find the area of the not shaded portion
3 X 3 = 9 in^2 (area of the not shaded portion)
- so, now that we have both areas, we just have to subtract them to find the area of the shaded portion
72 - 9 = 63
- - > 63 inches squared
