Solution

## 1. Area of Kalahari, South Africa [∵standard form a×10k] =932400=932400.00=9324×102=9.324×103×102=9.324×105 2. Area of Thar, India =199430=199430.00=19943×101=1.9943×104×101=1.9943×105 3. Area of Gibson, Australia =155,400=155400.00=1554×102=1.554×103×102=1.554×105 4. Area of Great Victoria, Australia =647,500=647500.00=6475×102=6.475×103×105=6.475×105 5. Area of Sahara, North-Africa =8,598,800=8598800.00=85988×102=8.5988×104×102=8.5988×106 Two numbers written in scientific notation can be compared. The number with the larger power of 10 is greater than the number with the smaller power of 10. If the powers of ten are the same, then the number with larger factor is the larger number. Hence, the required ascending order of the size will be Gibson, Australia < Thar, India < Great Victoria, Australia < Kalahari, South-Africa < Sahara, North-Africa
