Answer:
Length = 45.37 in
Width = 30.56 in
Step-by-step explanation:
Let the width of the picture be 'w' inches.
Given:
Perimeter of the picture is,
Length is 15.75 inches shorter than twice the width. So, length is:

Plug in the values of 'l' and 'P' and solve for 'w'. This gives,
Therefore, the width of the rectangular picture is 30.56 inches.
Length of the picture is,
So, length of the picture is 45.37 inches and width is 30.56 inches.
