We have seen that If the length of a rectangle increases by `10 %` and its breadth. decreases by `10 %` then the area decreașes by `1 %`. Instead of this, If the length decreases by `10 %` and the breadth increases by `10 %` how does the area change?

If the length of a rectangle is increased by 2m and breadth decreased by 1m, the area will decrease by 6m^2 . If the length is decreased by 3m and breadth increased by 3m area will increase by 9m^2 . Find the length and breadth.

If the length of a rectangle is increased by 2m and breadth decreased by 1m, the area will decrease by 6m^2 . If the length is decreased by 3m and breadth increased by 3m area will increase by 9m^2 . Form two equations with X and Y.

If the length of a rectangle is increased by 2m and breadth decreased by 1m, the area will decrease by 6m^2 . If the length is decreased by 3m and breadth increased by 3m area will increase by 9m^2 . If the length is taken as X , and breadth Y. Find the area of first rectangle.

If the length and breadth of a rectangle are increased by 10 % , by how much percent would the area increase? What if length is increased by 10 % and the breadth decreased by 10 % ?

The length of a rectangle is 10 centimetres and its breadth Is 4 centimetres. What is its perimeter?.
