Answer to Problem 10STP
The width of the stone path is:
Explanation of Solution
Given information:
The width of the walkway in feet:
The width of the stone path is
If the combined area of the garden and the stone path is
Calculation:
Consider the provided statement:
First find the area of the inner rectangle:
The length of the inner rectangle:
The width of the inner rectangle:
Then the area of the rectangle in general:
Then apply the values in the formula of area of rectangle:
Now find the combined area of garden of the stone path:
Now the new length of the combined rectangle is:
Now the new width of the combined rectangle is:
Apply the values in the formula of the area of rectangle:
Simplified further:
Simplified the equation by :
By the further simplification use the quadratic method:
Take this term for positive:
Take this term for negative:
So, width of the stone path is:
Hence, the width of the stone path is:
