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 answer
A) 1000  B) 1250  C) 1500  D) 1600  E) 2000

Rationale: to begin , find the area of each of the two sections by multiplying the lengths of the sides : 30 feet × 40 feet = 1200 square feet 60 feet × 80 feet = 4800 square feet the total area that needs sod has an area of 1200 + 4800 = 6000 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 : 6000 ÷ 4 = 1500 correct answer c ) 1500
Answer: C
