**ANSWERS:**

**Perimeter = 40 cm**

Length of each side = 40/4 = 10cm**Area = 25 sq. cm**

Length of each side = 5cm**Perimeter of a square = 4 x side = 4 x 1 = 4 sq.cm****Perimeter = 100 cm**

Length of each side = 100/4 = 25 cm**Area of a rectangle = l x b = 20 x 10 = 200 sq.cm.****Perimeter of a regular hexagon = 6 x side = 6 x 5 = 30 m****Perimeter = 10 + 12 + 20 = 42 cm****Area = 120 sq. cm**

Length = 20cm

Breadth = 120/20 = 6cm**Perimeter = 2 (l + b) = 2 (30 + 20) = 2 x 50 = 100 m**

Cost of fencing = 100 x 30 = 3000 rupees**Perimeter of a square = 4 x side = 4 x 75 = 300m**

If she takes 5 rounds daily, total distance covered = 300 x 5 = 1500m**Perimeter = 2 (l + b) = 2 (45 + 20) = 2 x 65 = 130m****Area of square tile = side x side = 10 x 10 = 1000 sq. cm**

Area of the floor = 750 x 500 = 375000 sq. cm

Number of tiles needed = 375000/1000 = 375**Perimeter = 50cm**

Length of third side = 50 – (15 + 20) = 50 – 35 = 15 cm**Perimeter = 4 x side = 4 x 200 = 800m**

Cost of fencing = 800 x 25 = 20000 rupees**Area of a rectangle = l x b = 12 x 8 = 96 sq. m**
