Hii There!!!

It's simple

Given, Two sides of rectangle i.e, Perpendicular = 15 cm and base = 8cm

We also know that, each angle in a rectangle = 90°

Hence, by using Pythagoras Theorem, we will find hypotenuse .

So, Hypotenuse^2 = Base^2 + Perpendicular^2

=> H^2 = 8^2 + 15^2

=> H^2 = 64 + 225

=> H^2 = 289

Or H = √289

=> H = 17 cm

Hence, Hypotenuse (Diagonal ) = 17cm
