Problema Solution

The width of a rectangle is 29 centimeters. Find all possible values for the length of the rectangle if the perimeter is at least 752 centimeters. Let L represent the length.

Answer provided by our tutors

let 'p' represent perimeter, 'l' represent length and 'w' represent width:

p = 2(l*w)


w=29 is given, as is p>=752


we use the following inequality to solve for possible values of 'l':

752<=2(l*29)

solving for 'l' we have l>=12.96


the perimeter should be no less than 13 centimeters
