To calculate: The width of mat that surrounds the photo.
Answer to Problem 53E
The width of mat that surrounds the photo is
Explanation of Solution
Given information:
The dimensions of frame are 3 feet by 4 feet. The area of photo is 6 square feet. There must be uniform width of the map that surrounds the photo.
Calculation:
Consider the provided information dimensions of frame are 3 feet by 4 feet. The area of photo is 6 square feet. There must be uniform width of the map that surrounds the photo.
Let from each side a width of x is left out to frame the photo.
So, the length of photo is
Therefore, area of photo is 6 square feet so,
Simplify it further as,
Apply the zero property.
Either
If
So reject
So, width of mat is
Thus, the width of mat that surrounds the photo is
