Answer: the total area of the enlarged garden is 324 square feet
Explanation:
Lisa square garden has an area of 64 square feet. The formula for determining the area of a square is expressed as
Area = Length²
Length = √Area
Therefore, Length of each side of Lisa's garden is
√64 = 8 feet.
Lisa increases each side of her square garden by 5 feet. It means that the length of each side of the enlarged garden is 8 + 5 + 5 = 18 feet
Therefore, the total area of the enlarged garden would be
18² = 324 square feet
