What is the answer of this question ?

Length = 51 centimeters

Width = 19 centimeters

Step-by-step explanation:

Length = l

Width = w

Length is 3w - 6

l = 3w - 6

P = 2l + 2w

The perimeter is given, plug in the values.

140 = 2(3w - 6) + 2w

140 = 6w - 12 + 2w

140 + 12 = 8w

152 = 8w

w = 19

The width is 19cm.

l = 3w - 6

l = 3(19) - 6

l = 57-6

l = 51

The length is 51 cm.

Step-by-step explanation:

let the width be x

Let's find the length

Perimeter of a rectangle

given that,

so,

therefore,

width = 19 cm

length = 3x-6

= 51 cm
