1. The ______of a polygon is the sum of the lengths of all its sides.

2. Perimeter of an equilateral triangle = 3 × _____.
3.The side of a square is 10 cm. 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
4.Two regular hexagons of perimeter 30 cm each are joined as shown in figure.

The perimeter of the new figure is

(a) 65 cm (b) 60 cm (c) 55 cm (d) 50 cm

5. Assertion (A): Perimeter of an equilateral triangle = 2 × length of side
Reason (R): Perimeter is the length of the boundary of a shape.

(a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true but R is not the correct explanation of A.
(c) A is true but R is false.

(d) A is false but R is true.
6.Find the perimeter of the given figure.
