A rectangle does not have a diameter, only circles or similar obects have diameters. A rectangle has a diagonal which is obtained by joining two opposite corners. Any two adjacent sides of the rectangle together with the diagonal form a right angled triangle and so the length of the diagonal can be derived using Pythagoras's theorem.

A rectangle is an elongated square. It doesn't have a diameter; only circles have diameters.


How do you calculate the diameter of a rectangle?

A rectangle does not have a diameter, as such, but the diagonal is similar enough. If the sides of a rectangle are x cm and y cm then, using Pythagoras's theorem, the diagonal is sqrt(x2 + y2) cm.


Can you fit a rectangle 21.5x 24 in a 27 diameter circle?

No. The diagonal of the rectangle is a little over 32.2, and nothing that long can fit into a circle with a diameter of 27.

How do you work out the diameter of a rectangle?

The diameter of a rectangle is the same as its diagonal (angle in a semicircle is a right angle). So the diagonal forms a right angled triangle with the diagonal as the hypotenuse and two sides of the rectangle (a length and a breadth) forming the legs of the triangle. If the lengths of the sides of the rectangle are known, a simple application of Pythagoras's theorem given the measure of the diagonal.
