Answer:
The picture frame is 0.50 inches wide.
Explanation:
Consider the image below.
The inner rectangle represents the image of Jennifer's boyfriend.
And the outer rectangle represents the outside of the picture frame.
The width of the picture frame can be computed by subtracting the measures of the respective sides of the two rectangles.
Compute the width using the breadths of the two rectangles as follows:
Width = (Outer Breadth - Inner Breadth) ÷ 2
= (5 inches - 4 inches) ÷ 2
= 1 inch ÷ 2
= 0.50 inches.
Compute the width using the length of the two rectangles as follows:
Width = (Outer Length - Inner Length) ÷ 2
= (7 inches - 6 inches) ÷ 2
= 1 inch ÷ 2
= 0.50 inches.
Thus, the picture frame is 0.50 inches wide.
