The length of a rectangle be equal to the side of a square and breadth of the rectangle is 30% less than its length then find the ratio of the area of rectangle to that of the square.?
Assume the rectangle's length is L
Then breadth = 30% less than L = 70% of L = 7L/10 m. Area of rectangle lb = 7/10 * L2 Side of the square = a m
Area of square = a2 sq.m
Ratio = Area of rectangle : Area of square
=(7/10)L2 : a2 (Here length of the rectangle is equal to side of the square) = 7/10 : 1 = 7:10
