A(n,s)=(ns^2)/(4tan(180/n)), n=number of sides, s=side length
A(8,4.6)=(8*4.6^2)/(4tan22.5)
A(8,4.6)=42.32/tan22.5 m (exact)
A(8, 4.6)≈102.17 m^2 (to nearest hundredth of a square meter)
WRITE EQUATIONS....
f = k÷ g (inversely proportional....)
∴ if f= 40 and g= 5 K= (40×5) =200
now that u have k... and given g = 10...u can substitute to find f
f= 200÷10 =20
so f = 20
If it is a square then find the square root of 400. Which would get you 20. So 20 is the length of one side since it is a square you multiply 20 by 4 to get 80. The perimeter is 80 feet
