Question

Australia is approximately 3,000,000 square

miles in area. Sand dunes cover 40% of the land.

How much of Australia is

covered by sand dunes?

Answer 1

1,200,000 square miles

Explanation:

Given data:

Total land = 3 000 000

40% is covered by sand dunes

Land covered by sand dunes is 40% of the total area therefore

Land covered by sand dunes=(40/100) * 3000000

Land covered by sand dunes= 0.4 * 3000000

Land covered by sand dunes= 1 200 000
