Question

Find the diagonal of a rectangle whose length is 40cm and breadth 9 cm​

Answer 1

Answer:

Diagonal of rectangle is 41 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 = (40)² + (9)²

=> (Diagonal)² = 1600 + 81

=> (Diagonal)² = 1681

=> Diagonal = 41 cm

Hence,

Diagonal of rectangle is 41 cm.
