The length of a rectangle is increased by 15% and the breadth is reduced by 15%. Let’s work out in percentage the increase or decrease of area.

If the length of a rectangle is increased by 3 metres and the breadth is decreased by 3 metres, then the area of the rectangle is decreased by 18 sq .meters . Again , if its length is increased by 3 metres and the breadth is increased by 3 metres, then area of the rectangle is increased by 60 sq. metres . Find the length and breadth of the rectangle.

If the length of a rectangle is decreased by 5 metres and the breadth is increased by 3 metres the area is decreased by 9 sq metres but if the length is increased by 3 metres and the breadth by 2 metres, the area is increased by 67 sq.metres. Find its length and breadth.

If the length of a a rectangular park be increased by 2 metres and the breadth be deceased by 2 metres , then the area of the park is decreased by 26 sq . Metres . Again , if the length be decreased by 1 metre and the breadth be increased by 2 meters, then the area of the park is increased by 33 sq. metres . Find the area of the rectangular park.

If the length of a rectangular field is doubled and its breadth is halved (i.e, reduced by 50% ) . What is percentage change in its area ?

The income of Amina Bibi was increased by 20% and later decreased by 20%. Let's work out the total change of percentage of her income.

The length of a rectangle is (4x + 1)m and breadth is 3x m. Let's calculate the area of the rectangle.
