DETERMINE the length, X, of the lean-to roof attached to the side of the cabin. 3.0m, 1.0, 2.0,5.0 and 4.0
this makes no sense.
To determine the length, X, of the lean-to roof attached to the side of the cabin, you need to provide more information or clarify the given measurements. The measurements you provided (3.0m, 1.0, 2.0, 5.0, and 4.0) don't seem to have a clear arrangement or definition.
To calculate the length, X, you typically need the measurements of at least two sides of the lean-to roof. These measurements could be the width, height, or angle of the roof.
If you have the measurements in a different format or if there are any additional details, please provide them, and I'll be glad to help you determine the length of the lean-to roof.
