Solution
The correct option is B54m2 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.
