The length of a rectangle is twice the width. Find the width if the perimeter is 60 centimeters. Define a variable, write an equation, and solve the problem.

Respuesta :

width = w

length = 2w

perimeter = 2w + 2 l

perimeter = 2w +2(2w)

60 = 2w + 4w

60= 6w

60=6w

w = 60/6 = 10

length = 10x2 = 20

10+10+20+20 = 60

The dimensions (length and width) of the rectangle are 20 and 10 centimeters respectively.

  • Let the length of the rectangle be L.
  • Let the width of the rectangle be W.

Given the following data:

  • Perimeter of rectangle = 60 centimeters

Translating the word problem into an algebraic equation, we have;

[tex]L = 2W[/tex]

To find the dimensions (length and width) of the rectangle;

Mathematically, the perimeter of a rectangle is given by the formula;

[tex]P = 2(L + W)[/tex]

Substituting the values into the formula, we have;

[tex]60 = 2(2W + W)\\\\60 = 2(3W)\\\\60 = 6W\\\\W = \frac{60}{6}[/tex]

Width, W = 10 centimeters

Next, we would find the value of L;

[tex]L = 2W[/tex]

Substituting the value of W, we have;

[tex]L = 2(10)[/tex]

Length = 20 centimeters

Therefore, dimensions (length and width) of the rectangle are 20 and 10 centimeters respectively.
