Let the side of the first square be x and the another square be y.


(1)


Given that Sum of areas of two squares is 468m^2.


We know that Area of square = (S)^2


= > x^2 + y^2 = 468 ------- (1)



(2)


Given that Difference of their parameters is 24m.


We know that perimeter of the squares = 4S.


= > 4x - 4y = 24


= > x - y = 6


= > x = 6 + y ------- (2)


Substitute (2) in (1), we get


= > (6 + y)^2 + y^2 = 468


= > 36 + y^2 + 12y + y^2 = 468


= > 2y^2 + 12y + 36 = 468


= > 2y^2 + 12y - 432 = 0


= > y^2 + 6y - 216 = 0


= > y^2 - 12y + 18y - 216 = 0


= > y(y - 12) + 18(y - 12) = 0


= > (y + 18)(y - 12) = 0


= > y = 12, -18


Since, y cannot be negative. so y = 12.


Substitute y = 12 in (1), we get


= > x^2 + y^2 = 468


= > x^2 + 144 = 468


= > x^2 = 468 - 144


= > x^2 = 324


= > x = 18



Therefore, the sides of two squares are 18cm and 12cm.



Hope this helps!
