Question about Lenovo ThinkPad R60 with Wireless Wide Area Network (ThinkPad R60_WWAN_Standard_123N)
This is a math problem?
the area of the old square was 100, the new one is 225
say the old squares side was X, so the area was X^2
the new square has area 2.25 X^2
take the square root to find the side of the new square: 1.5 X
so we know that the side of the old square plus 5cm is the side of the new square. so X + 5 = 1.5 X
solve that to find X = 10,
so the area of the old square was X ^ 2 = 100
and the area of the new square is 2.25 X ^ 2 = 225 :)
