B. 15 cm

C. 20 cm**Which of the following fields having the greatest perimeter?**

A. A triangular field with lengths 3m, 5m and 4m

B. A square field with length of sides 3m.

C. A rectangular field with length 3m and breadth 5m**Length of the boundary is known as ————-**

A. Area

B. Perimeter

C. Volume

Answer the following:**A rectangular field has length 35m 50cm and breadth 25m. How long is the boundary of the field?****Find the perimeter of a square whose length of side is 25m.****Perimeter of a square carrom board is 320m. Find the length of each side?****Find the perimeter of a square whose length of side is 20cm?****A hockey field is 91 metres 40cm long and 55 metres wide. How long is the boundary of the field?**

**ANSWERS:**

**36m****100cm****20cm****A rectangular field with length 3m and breadth 5m****Perimeter****Given length = 35m 50cm, breadth = 25m**

Length of the boundary = 35m 50cm + 35m 50cm + 25m + 25m = 70m 100 cm + 50m

= 71m + 50m = 121m**Length of the side of a square = 25m**

Perimeter of the square = 25 + 25 + 25 + 25 = 100m**Given perimeter = 320m**

Length of each side = 320/4 = 80m**Length of a side = 20cm**

Perimeter of a square = 20 + 20 + 20 + 20 = 80cm**Given length = 91m 40cm, breadth = 55m**

Perimeter = 91m 40cm + 91m 40cm + 55m + 55m = 182m 40cm + 110m = 292m 80cm
