Answer to Problem 16Q
The required equation is
Explanation of Solution
Given information:
The amount of area to the area of the patio by expanding the existing patio = 464 square feet
Calculation:
The area of the existing patio is:
The given difference between the area of the extended area
Hence, the required equation is
c.
To calculate: The distance x for which the length of the patio should be expanded.
c.

Answer to Problem 16Q
The required distance x for which the length of the patio should be expanded is 8 feet.
Explanation of Solution
Given information:
The amount of area to the area of the patio by expanding the existing patio = 464 square feet
Formula used:
Calculation:
The area of the existing patio is:
The given difference between the area of the extended area
Solve the above equation for x by using the quadratic formula
Solve for x .
And,
But the distance cannot be negative.
So,
Hence, the required distance x for which the length of the patio should be expanded is 8 feet.
