Question

1.If the length and breadth of a rectangle are doubled, how many times the perimeter of the old rectangle will that of the new rectangle be?​

Answer 1

Answer:

The perimeter of old triangle will be half of the new triangle

Step-by-step explanation:

Suppose that length of a triangle is 2cm and breath is 3 cm.

So Permiter is equal to 2*(2+3)=10

Now the breadth and length are found.

so Permiter=2*(4+6)=20

So now the perimeter of old triangle is half of me triangle if length and breadth are doubled
