Question

The length of a rectangle is 2 inches less than 3 times the number of inches in its width. If the perimeter of the rectangle is 28 inches, what is the width and length of the rectangle?

{Width_________________ a0in., Length_______________ a1in.}

Answer 1

let the width be w

and then the length is

l = 3w - 2

so

P=2(l + w)

or

28 = 2(w + 3w -2)

now solve for w...

hope it helps

Answer 2

so is W=4

Answer 3

yep... the width is w and the length is 3*4 - 2

Answer 4

lol..opps width is 4

Answer 5

wait what?

Answer 6

well the width is 4.... thats correct

and you know the length

l = 3w - 2

so make the substitution to find the length

l = 3x4 - 2

l = 10

Answer 7

okay thank you
