Answer: he would need 77 scoops of fertilizer.
Explanation:
The measure of Horalco's garden is
10 1/2 ft by 5 1/2 ft. Converting to improper fraction, it becomes 21/2 ft by 11/2 ft. The garden is rectangular in shape and the formula for determining the area of a rectangle is expressed as
Area = length × width.
Therefore, area of the garden is
21/2 × 11/2 = 231/4 ft²
He needs 1 1/3 scoops of fertilizer for each square foot of the garden. Converting to improper fraction, it becomes 4/3 scoops. Therefore, the number of scoops of fertilizer that Horaclo need for the entire garden is
4/3 × 231/4 = 77 scoops of fertilizer.
