To write: The system of linear equations for the given scenario and solve it to obtain dimensions of rectangle.
Answer to Problem 32PPE
l = 13 and w = 4
Explanation of Solution
Given information:
Following rectangle is given:
Perimeter of rectangle = 34 cm
The length ( l ) of rectangle is 5 more than twice the width ( w ).
Calculation:
Based on given information
Also
Thus system of equations for the given scenarios is as follows:
Let’s solve above two equation using substitution method.
Substitute
Now simplify above equation.
Use above value ofw in equation
Therefore the solution is l = 13 and w = 4.
Check
Area of rectangle =
