Answer:

Area of desert a = 600,000 square miles
Area of desert b = 200,000 square miles.

Explanation:

Let area of desert a be #x# square miles and let area of desert b be #y# square miles.

We have:
#x=3y#
#x+y=800000#

Putting x as 3y in second equation, we get:
#(3y)+y=800000#
#4y=800000#
#y=200000#

We know that #x=3y# so,
#x=3xx(200000)#
#x=600000#

Hence, area of desert a is 600,000 square miles, and area of desert b is 200,000 square miles
