Question

the side of a square is 12 cm. How many times will the new perimeter become if the side of the square is trebled?​

Answer 1

Answer:

3 times

Step-by-step explanation:

The formula for finding the perimeter if a square= 4 x side

therefore, to find the answer we have to find the old and new perimeter and compare them.

OLD PERIMETER

= 4 x 12

= 48

NEW PERIMETER

=  4 x 36 (12 x 3)

= 144

NOW LET'S FIND HOW Many TIMES THE NEW PERIMETER IS :-

therefore 48 x X = 144

                 X        =144

                              48

                   X      = 3
