Question

Size of a tv screen is defined by the length of its diagonal if the length of and breadth of the tv screen are 24 cm and 10 cm what is the size of the tv

Answer 1

Answer:

We use pythagoras theorem to find the diagonal

Let x be the size/diagonal

24² + 10² = x²

576 + 100 = x²

x² = 676

x = √676

x = 26 cm

Size of the tv = x = 26 cm
