Question

Find the diagonal of a rectangle whose length and breadth are 12 cm and 5 cm?

Answer 1

its root of 12^2 +5^2

Answer 2

Answer:

Diagonal of rectangle is 13 cm.

Step-by-step-explanation:

The diagonal of rectangle is like a hypotenuse.

So, by Pythagors Theorem

(Hypotenuse)² = (Length)² + (Breadth)²

=> (Diagonal)² = (12)² + (5)²

=> (Diagonal)² = 144 + 25

=> (Diagonal)² = 169

=> Diagonal = 13 cm

Hence,

Diagonal of rectangle is 13 cm.
