Let x be the side of the smaller square

Then (x+3) will be the side of the larger square

x2+(x+3)2  = 149

2x2+6x+9 =149

2x2+6x -140 =0

x2+3x-70=0

x2+10x-7x-70=0

x(x+10)-7(x+10)=0

(x+10)(x-7) =0

X= 7 or x=-10

X=-10 is not admissible

Thus the smaller square has side 7

Thus the larger square has side 10
