The perimeter of a bigger square is 12 m more than the perimeter of a smaller square than the perimeter of a smaller square . three times the area of the
smaller square is 11m square more than the area of the bigger square . find the length of bigger square

plz improve the question ... it is not clear!


The Brainliest Answer!
Let the length of side of smaller square be 'y' and the bigger be 'x'. 4x=12+4y, x=3+y, area of bigger square =x^2, area of smaller square=y^2, 3y^2=11+x^2, by substituting, 3y^2=11+(3+y)^2, y^2 -3y-10=0, "y=5" that is, length of the smaller one is5, x=5+3=8. therefore the length of the bigger square is 8.
