Answer:
1022.25 square feet
Step-by-step explanation:
The length and width sum to half the perimeter, so the length is ...
P/2 -W = length = 134/2 -23.5 = 43.5 . . . . feet
The area is the product of length and width, so is ...
A = LW = (43.5 ft)(23.5 ft) = 1022.25 ft^2
The area of the garden is 1022.25 ft^2.
