Question

If the length and breadth of rectangle both made half, then the perimeter of rectangle is how many times of given rectangle?

Answer 1

let length and breadth of the original rectangle be 'l' and 'b' respectively
then its perimeter will be 2( l+b) ......(1)
the length and breadth of the new rectangle which is formed by making half the length and breadth of the original rectangle is l/2 and b/2
 now perimeter of the new rectangle = 2( l/2+b/2)
 ⇒2( l+b/2)  ⇒ l+b.....(2)
 from(1) and (2),
 we observe that new rectangle formed is half the perimeter of the original rectangle..
answer = half times
 hope u understood the answer
