A farmer divides his ranch into 10 equal squares. The side length of each square section is 20 m. Calculate the total area of the ranch.

Area = (side)^2

Area = (20cm)^2

Area = 400cm^2 = the area of one square.

Let T = total area

T = 10(Area)

T = 10(400cm^2)

T = 4,000cm^2

Done.

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.
