Answer» GIVEN, the length and breadth of a rectangle are in the ratio 3:2 RESPECTIVELY. Given, the length and breadth of a rectangle are in the ratio 3:2 respectively.Then let the length and breadth of the rectangle be 3x,2x respectively. Given, the length and breadth of a rectangle are in the ratio 3:2 respectively.Then let the length and breadth of the rectangle be 3x,2x respectively.If the sides of the rectangle are extended on each side by 1 m then length and breadth will be 3x+1 m and 2x+1 m. Given, the length and breadth of a rectangle are in the ratio 3:2 respectively.Then let the length and breadth of the rectangle be 3x,2x respectively.If the sides of the rectangle are extended on each side by 1 m then length and breadth will be 3x+1 m and 2x+1 m.According to the problem, Given, the length and breadth of a rectangle are in the ratio 3:2 respectively.Then let the length and breadth of the rectangle be 3x,2x respectively.If the sides of the rectangle are extended on each side by 1 m then length and breadth will be 3x+1 m and 2x+1 m.According to the problem,2
or, 20x+10=21x+7 or, 20x+10=21x+7or, x=3. or, 20x+10=21x+7or, x=3.So length and breadth are 9,6 m respectively. or, 20x+10=21x+7or, x=3.So length and breadth are 9,6 m respectively.Now AREA of the rectangle be 9×6=54 m or, 20x+10=21x+7or, x=3.So length and breadth are 9,6 m respectively.Now area of the rectangle be 9×6=54 m 2 or, 20x+10=21x+7or, x=3.So length and breadth are 9,6 m respectively.Now area of the rectangle be 9×6=54 m 2 . |
