Question

The sides of a rectangle are 12 cm and 16 cm. Find the length of its diagonal.​

Answer 1

Answer:

Let the length of the diagonal be 'x'

_______________________

Then:-

$→ {x}^{2} = {(12)}^{2} + {(16)}^{2}$

$→ {x}^{2} = 144 + 256$

$→ {x}^{2} = 400$

$→ {x} = 20$

_______________________

• Hence the length of diagonal is 20cm.

Hope it helps you ✔️

Answer 2

a² + b² = c²

where a is lenght and b is breadth and c is diagonal.

ATQ.

12² + 16² = c²

c = square root (12² + 16² )

c = sq. root ( 144 + 256 )

c = sq. root ( 400 )

c = 20

Lenght of diagonal is 20 cm.
