The perimeter of a rectangle is 80 cm.It's length is 2 less than double its breadth.Then what are the length and breadth of the rectangle |
| Answer» SINCE, Perimeter =2(l+b)Here LENGTH =l and breadth =bIf the length and breadth of a rectangle are doubled. then length =2L and breadth =2b ∴ perimeter of rectangle WOULD be 2(2l+2b)=4(l+b)=2.2(l+b)∴ if the length and breadth of a rectangle are doubled then its perimeter is also doubled. | |
