Pythagorean Theorem question

Question

A rectangle area has been painted on a playground surface. To verify that each corner forms a right angle, the designer measured each side: 60’ and 90”, respectively, and then measured the hypotenuse: 108”. Use the Pythagorean Theorem to verify if right angles are formed. Explain how you know.

Answer 1

right angles are not formed

60^2+90^2≠108^2

3600+8100≠11,664

11,700≠11,664
