Answer the following:**The length of the sides of a square garden is 30m. Find the perimeter of the garden.****The three sides of a triangle is 5cm, 4 cm and 3 cm. Find the perimeter of the triangle.****The perimeter of a square is 420m. Find the length of each side.****The length and breadth of a rectangular garden id 10m and 2 m respectively. Find the length of the boundary?****Convert:**

a) 2 km = ——- m

b) 5 m = ———cm**c) 7cm = ——— mm**

ANSWERS:

**1000m****700 cm****250g****Perimeter****855 cm****Length of the sides of a square = 30m**

Perimeter = 4 x 30 = 120m**Three sides of a triangle are 5cm, 4cm and 3cm**

Perimeter = 5 + 4+ 3 = 12 cm**Perimeter of a square = 420m**

Length of each side = 420/4 = 105 m**Given length = 10m, breadth = 2m**

Length of the boundary = 10 + 2 + 10 + 2 = 24 m**a) 2000m**

b) 500 cm

c) 70 mm
