It represents the distance diagonally between two opposite corners of a Television. (i.e. the distance between the bottom-left corner and the top-right corner)
After 14 hours, it will be 9:00 AM.
ABC = DEF
AB = DE , AC = DF & BC = EF ( means similar )
EF = 4times BC
So, the triangle DEF is 4times the triangle ABC
EF = 24 and BC = 6
So, AB = DE/4 = 32/4 = 8
The sum of the first 28 positive odd numbers is 724.
