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 % ?`

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.

The sides of a square are increased by 10 % to make a larger square. By what percent is the area increased?

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.

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?
