Question

A rectangle has a perimeter of 374 cm and a length of 65 cm.

What is the width of the rectangle?


122 cm

244 cm

309 cm

I don't know.

Answer 1

The width would equal 122cm

Answer 2

122 cm

Explanation:

The formula for the perimeter of a rectangle is:

`p=2(l+w)`

Where "l" represents length and "w" represents width.

We can plug in the given values into the equation:

`374=2(65+w)`

Distribute the 2 to everything inside of the parentheses:

`374=130+2w`

Subtract both sides by 130

`244 = 2w`

Divide both sides by 2

`w=122`
