Question

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.
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.
