Answer to Problem 100E
Slope
Perimeter will increase by 8 meters
Explanation of Solution
Given information: The length and width of a rectangular garden are given as 15 meters and 10 meters. A walkway of width
Formula used:
Slope of a linear function
Calculation:
Here the given equation is
By comparing above two equations we get, slope
If we increase the width of walkway by 1 meter, then new length will be
Here perimeter
