Question

What will happen to the perimeter of a rectangle if it's length is double and breadth remains the same?

Answer 1

Answer:

Perimeter increases by a magnitude twice that of initial length.

Step-by-step explanation:

Perimeter of rectangle = 2(L+B)

Taking initial length L and breadth B

Initial perimeter = 2(L+B)

Final length =2L and Final Breath =B

Final Perimeter= 2(2L+B)= 4L+2B

Final Perimeter-Initial Perimeter = 4L+2B-2L+2B = 2L

So we can conclude that the perimeter increases by a magnitude twice that of initial length.

Answer 2

Answer:

perimeter of rectangle=2(l+b)

interior length length and breadth equal to2(l+b) final length equal to 2L and final breath

final perimeter=2(2L+B)=2L

perimeter increases by a magnitude twice that of intial length
