The perimeter of a rectangle is 13 cm and its width is `(2) 3/4 cm .` – InterviewSolution

1.	The perimeter of a rectangle is 13 cm and its width is `(2) 3/4 cm .` Find its length.
Answer» We know the perimeter`(P)` of a rectangle is `2(l+b)`, where l is length and b is breadth or width. Here, `P = 13cm` `b = 2 3/4 cm = 11/4cm` So, `13 = 2(11/4+l)` `=> l = 13/2-11/4 = 15/4cm = 3 3/4cm`
