Answer: 23.548 feet
Step-by-step explanation:
Area = 60 square feet
Width = y
Length = y + 7yards
Note:
1 yard = 3 feet
7 yards = 21 feet
Area of rectangle = width × length
60 = y × (y + 21)
60 = y^2 + 21y
y^2 + 21y - 60
using the quadratic formula calculator, and choosing the positive output.
y = 2.548 feet
Therefore, width(y) = 2.548 feet
Length = (width + 21 feet)
Length =2.548 feet + 21 feet
Length = 23.548 feet
