Find the sides of two squares ,which contain together 12.25 hectares ,the sides of the squares being in the ratio of 3:4.

• lets say side of both square is 3a & 4a
  according to question : (3a)^2 +(4a)^2 = 12.25
  9 (a^2) +16 (a^2)= 12.25
  25 (a^2)=12.25
  (a^2)=.49
  a=.7
  Sides of two squares are 2.1 & 2.8
