⟩ A building with height D shadow up to G. A neighbor building with what height shadows C feet. |----|----|----|----|----|----|----| A B C D E F G H
this can be solved by using the rule of cross multiplication i guess....
to get a shadow of G ft the ht of the building should be D
hence, for the shadow to be C ft, the height of the building should be CxD/G
