Answer:

first of all square mean two number or double so if we multiple 15×15=225 and if we multiply 16×16=256 mean the number 240 lies between them what about number 15.5 lets try now 15.5×15.5=240.25 if you want to make sure so just take a square root of this number

[tex] \sqrt{240.25} = 15.5[/tex]

so 240 is product of (15.5)² note number after point is negligible
