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
