Answer:
The expression that gives the length of the pool is - 5
Step-by-step explanation:
Assume that the length of the pool is x feet
∵ The length of the pool is x feet
∵ The wide of the walkway around the pool is 5 feet
∴ The total length of the pool with the walkway = (x + 5) feet
∵ The area of the entire plot, including the walkway, is A square feet
∴ The area of the entire plot, including the walkway = A feet²
∵ The area of the square = (length)²
→ Substitute the length by (x + 5)
∴ The area of the entire plot, including the walkway = (x + 5)² feet²
→ Equate it by A
∴ A = (x + 5)²
→ To find x take square root for both sides
∵ =
→ Cancel the square root of the right side by power 2
∴ = x + 5
→ Subtract 5 from both sides
∵ - 5 = x + 5 - 5
∴ - 5 = x
→ x represents the length of the pool
∴ The length of the pool is - 5 feet
∴ The expression that gives the length of the pool is - 5
The answer is 100% true
