Question

if the length and the breadth of a rectangular are triple how many times the perimeter of the rectangle will that of the new rectangle be​

Answer 1

Answer:

answer will be 3 times

Step-by-step explanation:

perimeter of rectangle = 2(l + b)

if length and breadth are tripled

perimeter of rectangle = 2(3l + 3b)

= 2×3 (l + b)

= 6(l + b)

therefore perimeter of new rectangle will become 3 times of old one
