The Smiths want to fence their square garden, which has an area of 289 square feet. What would be the minimum amount of fencing needed to complete the project? A)68 feet of fencing B)17 square feet of fencing C)289 feet of fencing D)17 feet of fencing

68 feets of fencing

Step-by-step explanation:

Given that:

Area of square garden = 289 ft²

The side length of square garden can be obtained thus :

Area of a square = s²

Where s = side length

s² = 289

s = sqrt(289)

s = 17

Perimeter of square garden : 4s

Perimeter = 4* 17 = 68 feets

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
