Use Pythagoras:



Or note that 25 is 5 times 5 and 20 is 5 times 4, so the other leg of the triangle has to be 3 times 5 equals 15.

Shouldn't that be "How wide is the width?", or even better,
"How wide is the TV?"
--------------------
The length doesn't have a width. The width doesn't have a width.
The TV has a width.
