Question 652445

The area of the Sahara Desert is 7 times the area of the Gobi Desert. If the sum of their areas is 4,000,000 sq. miles, find the area of each desert. Having trouble with figuring out the equation. Thank you.


Let area of Gobi = G
Then area of Sahara = 7G


Sum of their areas = G + 7G, or 8G


Therefore, 8G = 4,000,000


G, or area of Gobi = {{{4000000/8}}}, or {{{highlight_green(500000)}}} sq miles


Area of Sahara = 4,000,000 - 500,000, or {{{highlight_green(3500000)}}} sq miles
