Question

if the length and breadth of a rectangle are doubledhow many times the perimeter of the old rectangle will that of the new rectangle be ?
​

Answer 1

For old rectangle

Length = L

Breadth = B

Perimeter (P1) = 2×(L+B)

For New

Length = 2L

Breadth = 2B

Perimeter (P2) = 2 × (2L+2B)

= 2 × (L+B) ×2

(P2) = 2 × (P1)

Answer 2

Answer:

Step-by-step explanation:

For first rectangle

=P1=2(l+b)

For second rectangle

=P2=2(l+b)

=P2=4(l+b)

After that we have to divide them

P1/P2 2(l+b)/4(l+b)

So, the answer is 2
