Question 1021835
Hi there,
Looking at your problem
I think that your rectangular frame
has 3 cross bars all = x
2p = the two lengths.
5x = 3 crossbars + top and bottom bars
2p + 5x = 100
2p = 100 - 5x
p = 100/2 - 5/2x
p = 50 - (5/2)x
............
I am not sure what the
covering entails, but if
it is just the whole area
this would = p * x (* = times)
Area = p * x
x = A/p
or
p = A/x
Hope this helps, but if not
please come back for more help. :-)
