Do you know that "rectangle" is a Matlab function???????????????????????????????????

Jaeho Seol on 18 Oct 2016

The function name 'rectangle' is duplicated with the built-in function. Cannot execute the test trial.

There was no correct solution since October, 12th, due to a defect in the test.

Thank you for renaming the function.
The test trials now can be executed correctly.

Awful wording: longer and shorter side, then width and length.

% x^2 = W^2 + L^2
% L =3*W

Could we solve these equations in matlab?

The problem statement should specify which (the width or the height) is the longer side of the rectangle.

David Verrelli on 14 Apr 2017

By convention, length is taken as greater than (or equal) to width if no other information is available. Not sure if the problem statement was rewritten, but currently there's no mention of "height".
