Answer 2

Answer:

2) 100 cm

Step-by-step explanation:

length of T.V. = 80cm

breadth of T.V. = 60 cm

if we draw a diagonal, there will be two right angles triangles.

now,

$diagonal \: = \sqrt{{(length)}^{2} + {(breadth)}^{2} }$

diagonal =

$\sqrt{ {8}^{2} + {6}^{2} } = \sqrt{64 + 36} = \sqrt{100} = 10$

Hope it would help.
