An interesting problem providing the sqrt(10) factor.

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.

Milan Petrovic on 21 Oct 2016

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

Milan Petrovic on 24 Oct 2016

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

great problem

function [width, length] = findRectangleDimensions(x)
width =sqrt(x^2/10);
length = 3*width;
end

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".
