Aright triangle has legs measuring 4.5 meters and 1.5 meters. the length of tge legs of a second triangle are proportional to the legs of the first triangle. which could be the lengths of the legs of the second triangle?

If the legs of both triangles are supposed to be proportional then they would be equal in length because that's what proportional means

so if the legs of one triangle are 4.5 and 1.5 then the other triangle "if proportional" would have legs with the same measurements which are 4.5 and 1.5

hope this answers your question

Ask math specialist. he know more. try it yourself,i know u can do it
