Question

The length of a rectangular mailing is 3 centimeters less than twice the width. The perimeter is 60 centimeters. Find the dimensions of the label.

Answer 1

Answer:

Width = 11 cm

Length = 19 cm

Step-by-step explanation:

We have;

• The perimeter of the rectangle as 60 cm
• The length is 3 cm less than twice the width
• Assuming the width is x cm

Then, the length is (2x-3) cm

But, the perimeter of a rectangle is given by, 2(L+W)

Therefore;

P = 2(L+W)

60 cm = 2 ( x + (2x -3))

60 = 2 ( 3x - 3)

60 = 6x - 6

6x = 66

 x = 11

2x - 3 = 19

Therefore;

Width = 11 cm

Length = 19 cm
