A square area of land is 144 square feet. What is the length of one side of a fence around the area? 1.)144 ft
2.)11ft
3.)-12ft
4.)12ft

4.) 12ft

Step-by-step explanation:

You solve the area of a square using the following equation:

Area of a square = s²

Plug in 144 for Area of a square:

144 = s²

Isolate the variable, s. Root both sides of the equation.

√144 = √s²

s = √144 = √(12 * 12) = 12

4.) 12ft is your answer.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
