The lengths of the sides of three squares are s, s+1, and s+2 . If their total area is 365 cm squared, find their total perimeter.

• 132 cm
  
  Sum of the area=s^2+(s+1)^2+(s+2)^2=365
  s^2+2s-120=0
  (s-10)(s+12)=0, s=10
  So sides of the squares are 10,11 & 12 cm.
  Total perimeter=4[10+11+12]= 132
