To find: the width of the frame using the given picture.
Answer to Problem 16PT
The width of the frame is
Explanation of Solution
Given:
The length of the picture is
Area of the picture and frame is
Concept used:
The quadratic equations are in the form:
Where
Calculation:
According to the given the length of the picture is
Area of the picture and frame is
Since, the frames and picture both have same shape rectangular therefore the are of the rectangle is:
Are of the rectangle form by the picture only is:
The value of
Now use the middle term factorization to solved the quadratic equation:
The distance cannot be negative therefore take
Hence, the width of the frame is
