Answer:
21 feet
Step-by-step Explanation:
Given that the new parking lot of the Grand Canyon National park has a square shape, which means all the lengths of the 4 sides of the parking lot are equal and the same, the perimeter of the parking lot = 4(L) = 84feet.
L = length of 1 side of the parking lot; perimeter = 84feet,
Therefore, solving for L (length of each side) would be:
84 = 4(L)
84/4 = L
L = 21ft
The length of each sides are all equal and each would be 21 feet long.
