Final answer:
To find the area the grass seed needs to cover, calculate the area of the pool and subtract it from the total lawn area. The pool area is (15/2)m * (13/4)m, which equals 24.375m^2.
Step-by-step explanation:
The student's question, "Gena wants to buy grass seed to cover her whole lawn, except for the pool. The pool is 7 1/2 m by 3 1/4 m. Find the area the grass seed needs to cover.", requires calculating the area of the pool to subtract from the total lawn area. First, we convert the mixed fractions to improper fractions; the pool dimensions become (15/2)m and (13/4)m.
To find the area of the pool, we multiply the length by the width: (15/2)m * (13/4)m. After simplifying, we have (195/8)m2 or 24.375m2.
To answer Gena's question, we would need the total lawn area (which isn't provided in the question). Assuming we have that total area value, we then subtract the pool's area (24.375m2) from the total lawn area to determine the area needing grass seed coverage.
