Answer:
40
Step-by-step explanation:
A square has equal sides, area is length times height, meaning the square root of 100 is one side of the square. [tex]\sqrt{100}[/tex] = 10, because 10(10) = 100
Now one side is 10 meters, a square has 4 equals sides so:
10(4) = 40
Or u can do it the long way, 10 + 10 + 10 + 10 = 40
