Answer:
Desert A: 400,000
Desert B: 3,600,000
Step-by-step explanation:
If desert b is 9 times bigger than desert a, we can classify desert b as the variable 9a. (To symbolize a * 9)
9a + a = 4,000,000
10a = 4,000,000
Divide 4 million by 10, and we get the area of desert a.
a = 400,000
Desert A has an area of 400,000.
We know Desert b is 9 times desert A, so we can just multiply the area of Desert A by 9 and we get Desert B's area.
400,000 * 9 = 3,600,000
Desert b has an area of 3,600,000.
