You need to estimate the square root of 200 ft². Rewrite 200 as 2 x 100, then square root of (2*100) is: 10*sqrt(2). The sqrt(2) = 1.414, so the length of each side of the square will be 10*1.414 = 14.14 ft or about 14 ft.
Answer:
10[tex]\sqrt{2}[/tex]
Step-by-step explanation:
(10[tex]\sqrt{2}[/tex] ) x (10[tex]\sqrt{2}[/tex] ) =200
A= l x w
