Question

The side of a square is 10cm. How many times will the new perimeter become if the side of the square is doubled?

(A) 2 times (B) 4 times (C) 6 times (D) 8 times

Answer 1

(A) 2 times

As we know that, perimeter of square = side × 4

= 10 × 4

= 40 cm

Given, side of square = 10 cm

The side of the square is doubled = 10 + 10

= 20 cm

Therefore, the new perimeter become 2 times the side of the square is doubled.
