The length of a rectangular piece of steel in a bridge is 3 meters less than double the width. The perimeter of the piece of steel is 48 meters. Find the length of the steel. Find the width.

Question

What steps or formula do I use to solve this problem.

Answer 1

You just write down what they told you.

width: w
length: 2w-3

Then you try to remember the way perimeter is calculated.

2(w + 2w-3) = 48

Then you solve for w, and use that to get the length.
