The answers are B , D , and F
Hey there!!
The formula for the area of a square - s²
where s = side
s² = 345
s = √345
s = 18.57 ft
Fence shall be three sides
So 18.57 × 3
The required answer = 55.71 ft
Hope my answer helps!
The value of s = 227 degrees. You can determine this because the area of a triangle is always 180 degrees. Since it is s-47, you add 47 to 180. This equals 227. Plug the number in and you get correct answer. 227-47=180
Hope this helps!
