Question

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

Answer 1

apply Pythagoras theorem
AC^2 = AB^2 + BC^2
AC^2 = 35^2 + 12^2
AC^2 = 1225 + 144
AC^2 = 1369
AC= √1369
AC= 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.
