Let x be side of square.
Area of square = x²

Side of square garden 1:   x _{1}  
Side of square garden 2:    x _{2}

Side of square garden 1, given its area of 1134 cm²
 (x_{1}) ^{2}  = 1134cm ^{2}
  \sqrt{ (x_{1} }) ^{2}   = \sqrt{1134cm ^{2} }
 x_{1} = \sqrt{(81)(14)cm^{2} }
 x_{1} = 9 \sqrt{14} cm

Side of square garden 2, given its area of  3150 cm²
( x_{2} ) ^{2} =3150 cm ^{2}
 \sqrt{( x_{2} ) ^{2} } =  \sqrt{3150 cm ^{2} }
 x_{2}  =  \sqrt{(225)(14) cm ^{2} }
 x_{2} = 15 \sqrt{14} cm

Combined sides (each side) = 9 \sqrt{14} cm + 15 \sqrt{14} cm
                                        = 24  \sqrt{14} cms.

Combined Perimeters:
Perimeter of Square = 4x
Perimeters (P) of the two square garden = 4(x _{1} ) + 4( x_{2} )
P _{1} +P _{2} = 4(9 \sqrt{14} cm)+4(15 \sqrt{14} cm)
P  _{1} +P _{2} = 36 \sqrt{14} cm + 60 \sqrt{14} cm
P _{1} +P _{2} = 96 \sqrt{14} cm
Combined Perimeters of the 2 Square gardens = 96 \sqrt{14} cm

magkaiba kayo ng sagotng guro ko. 25 square root of 14 yung sagot niya.
What do you think? You've correctly answered questions involving radicals here in brainly :-) square root of 1134 + square of 3150 yields 9 square root of 14 + 15 square root of 14 or 24 square root 14. Did I miss something? Please let me know so I could rectify.As far as I know, 9 + 15 is 24. :-)
Hndi ko napansin haha sorry XD
