the length of a rectangle is five times its width. if the perimeter of the rectangle is 84 cm, find its area. i really have no idea how to do these...

Question

anonymous · Answer

84=2(x+y) where x is length and y is width
now 84=2(5y+y)
solve it to get y
then put value of y in x=5y you will have dimensions of rectangle

im still pretty confused.. like i said i really dont get this stuff sorry..

anonymous · Answer

perimeter=2(lenght+bredth)
84=2(x+y) as given lenght = five time width so x=5y
then 84=2(5y+y) puting value of x in above equation
solve it you will get value of y
