The answer to yesterday’s greenhouse building problem is yes you can make a roof panel for the greenhouse from the remaining clear polycarbonate sheet after cutting a length for the wall.
There is 1m length of polycarbonate left and the minimum length needed for the roof is 0.72m or 72cm. Once we had worked out the required length we decided to leave an over hang on the roof and used the whole 1m piece.
To solve the problem you use the measurements provided and Pythagoras’ Theorem click here to see how to do this.
And here it is in real life.
