Answer:
∴ Area of Desert 1 = 9,000,000 square miles
Area of Desert 2 = 1,000,000 square miles
Step-by-step explanation:
let the area of Desert 1 = x
Let the area of desert 2 = y
Given:
x = 9y - - - - - - (1)
x + y = 10,000,000 - - - - -(2)
Replacing the value of x from equation 1 into equation 2:
x + y = 10,000,000
where x = 9y
9y + y = 10,000,000
10y = 10,000,000
y = 10,000,000 ÷ 10
y = 1,000,000 square mile
Next, finding x by putting the value of y into equation 1
x = 9y
where y = 1,000,000
∴ x = 9 × 1,000,000
x = 9,000,000 square miles
∴ Area of Desert 1 (x) = 9,000,000 square miles
Area of Desert 2 (y) = 1,000,000 square miles
