**1. What is the perimeter of an irregular hexagon with sides of length 5 cm, 8 cm, 4 cm, 6 cm, 7 cm, and 9 cm?**

a) 39 cm

b) 39.5 cm

c) 40 cm

d) 40.5 cm

**Answer:** a) 39 cm

**Explanation:** To find the perimeter of an irregular polygon, we need to add up the lengths of all its sides.

Substituting the given values, we get P = 5 + 8 + 4 + 6 + 7 + 9 = 39 cm.

**2. What is the perimeter of a regular octagon with sides of length 4 cm?**

a) 32 cm

b) 16 cm

c) 8√2 cm

d) 16√2 cm

**Answer:** a) 32 cm

**Explanation:** The formula for the perimeter of a regular polygon with n sides, each of length s, is P = n×s.

Substituting the given values, we get P = 8(4) = 32 cm.

**3. A kite has a perimeter of 28 cm. If one pair of adjacent sides has lengths of 6 cm and 6 cm, what are the lengths of the other two sides?**

a) 8 cm and 8 cm

b) 6 cm and 14 cm

c) 8 cm and 12 cm

d) 10 cm and 10 cm

**Answer:** a) 8 cm and 8 cm

**Explanation:** Since a kite has two pairs of adjacent sides that are equal in length, and the Perimeter is 28 cm, we can use the formula for the perimeter of a kite to set up an equation:

28 = 2x + 2y

28 = 2(6) + 2y

16 = 2y

y = 8 cm

So, the lengths of the other pair of adjacent sides are 8 cm and 8 cm.

**4. A circular track has a circumference of 440 metres. What is the length of one complete lap (the distance travelled when running around the track once)?**

a) 70 metres

b) 110 metres

c) 220 metres

d) 440 metres

**Answer:** d) 440 metres

**Explanation:** The circumference of the track is the distance travelled around the track once, so one complete lap is equal to the circumference = 440 metres

**5. Find the perimeter of a trapezium with parallel sides of length 5 cm and 7 cm, and non-parallel sides of length 4 cm and 6 cm.**

a) 20 cm

b) 22 cm

c) 24 cm

d) 26 cm

**Answer:** b) 22 cm

**Explanation:** The perimeter of a trapezium is the sum of the lengths of all its sides. In this case, the parallel sides have lengths of 5 cm and 7 cm, and the non-parallel sides have lengths of 4 cm and 6 cm.

Therefore, the perimeter is: Perimeter = 5 cm + 7 cm + 4 cm + 6 cm = 22 cm.

**1. What is the formula for finding the perimeter of a square?**

a) P = 2 x side

b) P = 4 x side

c) P = l + b

d) P = l x b

**Answer:** b) P = 4 x side

a) 18 cm

b) 16 cm

c) 15 cm

d) 20 cm

**Answer:** b) 16 cm

**3. What is the perimeter of a kite with side lengths of 8 cm and 12 cm?**

a) 16 cm

b) 20 cm

c) 32 cm

d) 40 cm

**Answer:** d) 40 cm

**4. What is the perimeter of an equilateral triangle with a side length of 6 cm?**

a) 12 cm

b) 9 cm

c) 18 cm

d) 15 cm
