The length of a rectangle is 3 less than 4 times

the width. The perimeter is 34. Find the length
and width.
Let
x = width
4x-3 = length
w=x
P = 2w + 2L
34 = 2x + 2(4x-3)
L=4x-3

  • x = width
  • 4x-3 = length

Perimeter = 2( Length + Width)

→34 = 2x + 2(4x-3)

→34 = 2x + 8x - 6

→34 = 10x -6

→10x = 34 +6

→10 x = 40

→x = 40/10

x = 4

  • Width is 4 unit and length is (4*4 -3) = 13 unit.

Hope this helped you!
