What is the equation for this problem? The length of a rectangle is 3 times the width. The perimeter is 96cm. Find the width and length.

• 3w + w = 96

• 2(3w) + w = 96

• 2(3w) + 2w = 96

• 3w + 2w = 96

How should you define the variables? The length of a rectangle is 3 times the width. The perimeter is 96cm. Find the width and length.

• Let w = width

  Let 3w = length

• Let x = length

  Let 3x = width

• Let w = width
