Question

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 prompts the user to input the length of the wire and outputs the length and width of the picture frame

Answer 1

Given Information:

Length of picture frame (L)=1.5*Width of picture frame(W)

Length of wire=Perimeter of rectangle

Perimeter of rectangle=2*(L+W)

Length of wire=2*(L+W)

Length of wire=2*(1.5*W+W)

Length of wire=2*(2.5*W)

Length of wire=5*W

W= Length of wire/5

Question:

Write a program that prompts the user to input the length of the wire and outputs the length and width of the picture frame?

The program is in C++

#include<iostream>

int main() {

float length; //variable to store length of rectangle

float width; //variable to store width of rectangle

float length_wire; //variable to store length of wire

// Taking length of wire as input

std::cout << "Enter length of wire";

std::cin >> length_wire;

//Computing length and width of picture frame

width= length_wire/5;

length=1.5* width;

// Printing length and width of picture frame

std::cout << "Length of wire is:"<<length;

std::cout << "width of wire is:"<<width;

return 0;
