Question

The area of a desert in Africa is 5 times the area of a desert in Asia. If the area of a desert in Asia is z square miles, express the area of a desert in Africa as an algebraic expression in z.
The area of a desert in Africa is how many square miles?

Answer 1

sahara is the largest desert

Africa, it measures approximately 3,000 miles (4,800 km) from east to west and between 800 and 1,200 miles from north to south and has a total area of some 3,320,000 square miles (8,600,000 square km); the actual area varies as the desert expands and contracts over time. The Sahara is bordered in the west by the Atlantic Ocean, in the north by the Atlas Mountains and Mediterranean Sea, in the east by the Red Sea, and in the south by the Sahel—a semiarid region that forms a transitional zone between the Sahara to the north and the belt of humid savannas to the south.
