Problema Solution
the length of a retangular frame is 53cm. for what widths would the perimeter be greater than 160cm
Answer provided by our tutors
Length of recangular frame =L= 53 cm;
Let the width= W;
Perimeter= 2(L+W)=2(53 + W)
If perimeter > 160 cm
then 2(53+W)>160
or 53+W>80
or W>80-53
or W>27 cm
If width is greater than 27 cm then perimeter greater than 160 cm
