Question

Elaine is making a flower garden with rows of flowers. The garden is 20 yards long. She wants a total of 7 rows of flowers that are all the same width. Which calculation should Elaine use to decide how wide to make each row?

Answer 1

Elaine should convert the garden length to feet, and then divide by the number of rows to find the width of each row. The resulting width will be approximately 8.57 feet per row.

Step-by-step explanation:

To decide how wide to make each row of her flower garden, Elaine should divide the total length of the garden by the number of rows she wants. The garden is 20 yards long, and she wants a total of 7 rows. To find the width of each row, the calculation she should use is:

1. Convert the total length of the garden into feet, since dimensions for smaller plots are often given in feet. Note: 1 yard = 3 feet.
2. Calculate the width of each row in feet by dividing the total length in feet by the number of rows.
3. If needed, convert the width of each row back to yards.

Step one results in 20 yards × 3 feet/yard = 60 feet. In step two, the width of each row is found by dividing 60 feet by 7 rows, which equals approximately 8.57 feet (or 8 feet and 6.84 inches) per row. Elaine might round this to a convenient measurement for practical gardening purposes.
