Maths question?

Hi. Im doing this assignment and i dont get one of these questions…

the assignment goes like this:

a )measure the length and wideth of a tv screen.

length=73

width=56

(done)

(b) draw a diagram and write the length and width on it (done)

(c) use pythagoras theorem to calculate the length of the diagonal. Measure the diagonal of the television screen.

pythagoras = 92

d) state what size tv screen you were measuring and how this advertised size compares with what you calculated in part (c) and part (d)…

i dont understand the last question.. any ideas?

You were measuring a 73 cm by 56 cm television screen. If the advertisement says the screen is as big as an elephant, then it’s exaggerating a teeny weeny little bit.

generally screens are advertised as the tube size rather than the viewing/picture size, and also this is the diagonal measurement.

when you consider the viewing size, there is a frame around the edge of the tube so there is a difference between these two figures.

in other words the tv you measured could have been advertised as a 1m screen because that is the size of the tube rather than the picture.

usually the size of the screen is measured diagonally but in inches it should be what you calculated
