Question

the length and breadth of a rectangle are 18 cm and 7 cm respectively if its length is halved and breadth is doubled then what is the new perimeter​

Answer 1

Answer:

Let the rectangle be 18 cm x 7 cm. Its perimeter = 2(18+7) = 50 cm.

If the length is doubled while the breadth remains the same, the perimeter = 2(36+7) = 96 cm.

Answer 2

Let the rectangle be 18 cm x 7 cm. Its perimeter = 2(18+7) = 50 cm.

If the length is doubled while the breadth remains the same, the perimeter = 2(36+7) = 96 cm.
