Question

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

Answer 1

• 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!
