Best ResponseYou've already chosen the best response.0the length of diagonal as a function of the length of the opposite sides, i feel like there is another variable involved but i think we can write a dependant function of these variables

Best ResponseYou've already chosen the best response.0like this this Z shape for instance

Best ResponseYou've already chosen the best response.0we can reshape the Z in many ways and still maintain 50 cm^2 i think there is no problem with that

Best ResponseYou've already chosen the best response.0but look at this, this illustration atleast tells us there have to be multiple possiblities

Best ResponseYou've already chosen the best response.0if i vary the angles between the lines that form Z, and vary the lengths incolved in eaach segment of the Z

Best ResponseYou've already chosen the best response.0i can think of ways the solution might be limited to just 1 answer, if it was asking is there a integer solution or something

Best ResponseYou've already chosen the best response.0oh maybe it comes down to the possible hypotenuse u can even form with a triangle

danica518

Best ResponseYou've already chosen the best response.0oh that could be helpful, we should consider the possible legs of a triangle and the maximum area they can produce

Best ResponseYou've already chosen the best response.2u mean that if v change the angles between the lines of z then v can have multiple solutions but v must keep the area in mind it may be possible that the area may change when we change the angles between the lines of z.

Best ResponseYou've already chosen the best response.0are there pair of similiar triangles for all quad?

Best ResponseYou've already chosen the best response.2they may be similar they may be nt

Best ResponseYou've already chosen the best response.2wait.. if any 2 triangles in the quad. r similar then the other 2 must also be similar so the triangle must be a parallelogram nd if it is a paralle.. then the 2 opposite sides r equal nd the diagonal would also be equal. and if u do the calculations taking the case of a parallelogram nd try to find side lengths then the answers would be like negative sides.
