Trish, this is the solution:
Let's recall the formula for calculating the area of a rectangle:
Area = Width * Length
Area of one planter = 4 1/4 * 1 2/3
Area of one planter = 17/4 * 5/3
Area of one planter = 85/12 inches²
But we have a 4 x 4 array of planters, that is 4² = 16 planters, therefore:
Area of the array = 85/12 * 16
Area of the array = 1,360/12
Area of the array = 113 1/3 inches² (Simplifying)
