A rectangle has a length of (x+10) centimeters and a width of x centimeters. If the perimeter is 32 centimeters, what is the length of the rectangle?

Respuesta :

Given:

Length of rectangle = (x+10) cm

Width of the rectangle = x cm

Perimeter = 32 cm

To find:

The length of the rectangle.

Solution:

We know that,

[tex]Perimeter=2(l+w)[/tex]

Where, l is length and w is width.

Substituting the values, we get

[tex]32=2((x+10)+x)[/tex]

[tex]32=2(2x+10)[/tex]

[tex]32=4x+20[/tex]

Subtract 20 from both sides.

[tex]32-20=4x[/tex]

[tex]12=4x[/tex]

Divide both sides by

[tex]3=x[/tex]

So, the length is

[tex]3+10=13[/tex]

Therefore, the length of the rectangle is 13 cm.
