Answer:
25.92 ft
Step-by-step explanation:
Since the area is 42:
A = B * H
Square root of 42 : 6.48074069841 (round down to 6.48)
Since the sandbox is a square, and we are looking for perimeter, multiply 6.48 * 4 = 25.92 ft
If you didn't round down to 6.48, it would not matter. When you round to the nearest hundreth, it still ends up being 25.92 ft.
6.48074069841 * 4 = 25.9229627936 (round down to 25.92)
You're welcome! :D
25.92 ft
the area of a square = s² ( s is the length of the side of the square )
here we have s² = 42 ( take the square root of both sides )
s = [tex]\sqrt{42}[/tex]
perimeter = 4s = 4 × [tex]\sqrt{42}[/tex] = 25.92 ft ( nearest hundredth )
