Answer:
424 cm²
Step-by-step explanation:
8 x 11 = 88 = 1 side
88 x 2 = 196 = 2 sides
11 x 6 =66 = 3 sides
66 x 2 = 132 = 4 sides
8 x 6 = 48 = 5 sides
48 x 2 = 96 = 6 sides
196 + 132+ 96 = 424
42,300
Answer:209ft
We let y be the unknown value, which is length of conduit.
200^2 + 60^2=y^2
40000 + 3600=y^2
43600=y^2
Square both side
y= sqrt(43600)
y= 208.8061 ft
y=209 ft
and 
are inversely proportional, there is some constant 
such that
and 
, we have
, you have
