Answer:
9.8ft
Explanation:
We are told in the question that Mrs Drew wants to build a sand box for her children. The shape is Square.
The formula for the Area of a square = L²
L = Side length
The area of the sandbox will be 97 ft.²
Hence,
97ft² = L²
Squareroot both sides
√97ft² = √L²
L = 9.8488578018 ft
Approximately to the nearest tenth (10th) = 9.8 ft
Therefore, the total length of wood mystery needed to make the sides of the sandbox is 9.8ft
