given , Area of the square is 225 sq-cm therefore, area of rectangle is 225/3=75 sq cm ..we know l*b=area of rectangle ....therefore 15*b=75 . we got the value of breadth =5 , then for area of square is (side)^2 =225 we get side =15 ...then the diff of breadth of rectangle and side of square is -10 cm

area of square = 3 times area of rectangle
225sq =3×225
=675sq.
length = 15cm
breadth=area/length
=675/15=45cm
side of a square=225/4=56.25
difference=length -side of a square
=56.25-45=11.25
225sq =3×225
=675sq.
length = 15cm
breadth=area/length
=675/15=45cm
side of a square=225/4=56.25
difference=length -side of a square
=56.25-45=11.25
