Andrea wants to fill in two sections of her
backyard with sod that must be purchased
in 2-x-2-foot squares. If the two sections
measure 30 x 40 feet and 60 x 80 feet, how
many squares of sod does she need to buy? Choose the correct choice from the following answers.
A) 1,000 B) 1,250 C) 1,500 D) 1,600 E) 2,000
To begin, find the area of each of the two sections by multiplying the lengths of the sides:   30 feet × 40 feet = 1,200 square feet   60 feet × 80 feet = 4,800 square feet   The total area that needs sod has an area of 1,200 + 4,800 = 6,000 square feet. Each individual   square is 2 feet by 2 feet, so each has an area of 4 square feet. Because all the numbers are   even, there will be no waste when the squares of sod are placed. Therefore, you just have   to find the number of squares needed by dividing:   6,000 ÷ 4 = 1,500   correct answer 1,500) 1,500
