Answer 1 :

Area of pool = 3M × 4M = 12M = 1200 CM

Area of 1 Tile  = 25 CM × 8 CM = 200 CM

1200 CM ÷ 200 CM = 6

So the Number of Tiles required is 6

Answer 2 :  

5 : 3 = 144M

8  = 144M

1 = 144 ÷ 8 = 18

18 × 5 = 90

18 × 3 = 54

The dimensions of the rectangular park is

Length = 90

Breadth = 54
