Question

F. 221
Find the diagonal of a rectangle whose length is 35 cm and breadth is 12 cm​

Answer 1

Step-by-step explanation:

Let the rectangle be ABCD.

Length = 35 cm

Breadth = 12 cm

By Pythagoras' Theorem,

DB^2 = AB^2 + AD^2

DB^2 = 35^2 + 12^2

DB = root of 1225+144

DB = Root of 1369

DB = 37 cm

Answer 2

Answer:

Diagonal of rectangle is 37 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 = (35)² + (12)²

=> (Diagonal)² = 1225 + 144

=> (Diagonal)² = 1369

=> Diagonal = 37 cm

Hence,

Diagonal of rectangle is 37 cm.
