Answer:
55 1/8
Explanation:
The total number of planters in the 3x3 array is 3 x 3 = 9. To find the total area covered by the planters, we need to multiply the area of one planter by the number of planters:
Area of one planter = base x height = 3.5 inches x 1.75 inches = 6.125 square inches
Total area covered by the planters = number of planters x area of one planter = 9 x 6.125 square inches = 55.125 square inches
Therefore, the area covered by the planters in the 3x3 array is 55.125 square inches.
