Answer 2

Answer:

the length of the diagonal is 17 cm.

Step-by-step explanation:

(Refer to the diagram attached below )

We are given that one of the sides is 15 cm long and other side (adjacent side) is 8 cm in length

We know that adjacent sides of a rectangle are perpendicular to each other.

So the given sides and diagonal of the rectangle form a right angled triangle.

Where the diagonal is the hypotenuse

Pythagoras Theorem: Base² + Altitude² = Hypotenuse²

=> 8² + 15² = Hypotenuse²

=> 64 + 225 = Hypotenuse²

=> 289 = Hypotenuse²

=> Hypotenuse = $\sqrt{289}$

= 17

So the length of the diagonal is 17 cm.
