The side of a square is 19 cm. How many times will the new perimeter
become if the side of the square is tripled?​

Answer 1

Step-by-step explanation:

Given:

The side of a square is 19 cm.

Therefore, it's Perimeter = 4a=4×19=76 cm.

To find:

It's Perimeter if the length of side becomes tripled or 3 times.

Solution:

Side of a square =19 cm.

Now, it is tripled=19×3=57 cm.

Therefore it's Perimeter=4×57=228 cm.

☆Hence the perimeter of square after length of side get tripled i.e 19 cm is 228 cm.

Alternate way:

We know that Perimeter of square is 76 cm when side length is 19 cm.

Now Side length got tripled ,therefore also got tripled =76×3=228 cm.
