A garage is 4m longer than it is wide and 1cm higher that it is wide. The longest pole which can fit inside the garage is 7.5m long. How wide is the garage (to 3 significant figures)?

Answer 1

First, you need to convert all units either to m or cm.

Then depending on the units you chose, you will get a quadratic in w the the coefficient of the w² term equal to 3.

Then solve the quadratic for w.
