Final answer:
The length of the brick wall in Daisy's flower garden is 62 feet.
Step-by-step explanation:
The length of the brick wall in Daisy's flower garden can be found by using the formula for the perimeter of a rectangle, which is P = 2(L + W), where P is the perimeter, L is the length, and W is the width. In this case, the width is 7 feet and the length is 24 feet. Plugging these values into the formula gives P = 2(24 + 7) = 62 feet.
