Question

The length of the school playground is 200m and 150m. Find the area of the playground in hectares.

Answer 1

Answer: 3 ha.

Explanation:

l = 200 m, b = 150 m.

Area = lb = (200 m)(150 m) = 30000 m²

Now, 1 ha = 10000 m²

So, area = (30000 m²)/(10000 m²) = 3 ha.

More:

• There are many units of measuring land. Like bigha, guintha, etc.
• Conversion:- 1 km = 10 hm = 100 dam = 1000 m = 10000 dm = 100000 cm = 1000000 mm.
• Similarly, in small units include nm (nano meter), µm (micro meter), pm (pico meter), etc.
