What geometric shape has 4 right angles and sides with two different lengths?

Answer 1

A rectangle.

As long as the sides that are opposite of each other are the same length(required to get the 90 degree angles) but both sets must be different lengths or else you get a square

Answer 2

A rectangle.

Opposite sides must have the same length in order for it to be 90 degrees all around but the two sets of opposite lines can have different lengths from each other
