The sides of a rectangle are in the ratio of 6 : 5 and its area is 1331 sq.m. Find the perimeter of rectangle.
Let 6x and 5x be sides of the rectangle 6x × 5x = 1331 11x2 = 1331 x2 = 1331/11 = 121 => x = 11 Length = 6x = 6 × 11 = 66 Breadth = 5x => 5 × 11 = 55 Perimeter = 2 (l+b) => 2 (66+55) = 121 m
