Question

Arod 28 centimetres long is to be bent to make a rectangle Can a rectangle of diagonal 8 centimetres be made?​

Answer 1

• As the discriminant is less than 0 that's why a rectangle of a diagonal 8 cm can not be made. Now for the rectangle to be possible the sum of the length and width is equal to 14. So one of the possible case is when length = 8 and width = 6
