Problem Statement for Picture Frame Program
A piece of wire is to be bent in the form of a rectangle to put around a picture frame. The length of the picture frame is 1.5 times the width. Write a program that asks the user to enter the length of the wire and outputs the length and width of the picture frame.
Part 1. Understand the ProblemThe problem
gets the length of the wire for the frame from the user. The ratio of length to width of the frame is a constant (1.5).
The length and width of the picture frame that are to be calculated and displayed.
The length of wire represents the perimeter of the rectangular picture frame. The equation for the perimeter of a rectangle is:
Perimeter = 2 * (length + width)
This is an equation with two unknowns, but the ratio of the lengthto the width (length = ratio * width) so substitute for length in the perimeter equation and solve for width:
Perimeter = 2 * (ratio * width + width)
ratio * width + width = Perimeter / 2
width * (ratio + 1) =…
