If the area of square is 225 cmsup2; and the breadth of rectangle is 20% more and the length is 30% more than the side of the square, then find the the area of rectangle.
Area of square = 225 cm2, Side of square = 15 cm Area of rectangle = l x b Length = 15 x 1.3 = 19.5 cm Breadth = 15 x 1.2 = 18 cm Area of rectangle = 19.5 x 18 = 351 cm2;
