Question

The width of a rectangle is 2 less than twice the length, x. If the perimeter is 44, what is the width?

Answer 1

Take the length as 'x'

Width = 2x - 2

Perimeter = 44 [ Formula = 2(l + w) ]

2 (l + w) = 44

2 (x + 2x - 2) = 44

2 (3x - 2) = 44

6x - 4 = 44

6x = 44 + 4

6x = 48

x = 48/6

x = 8 => length

Width = 2x - 2 = 2(8) - 2 = 14 units.

Hope it helps!
