use a proportion:
62"/36"=h/43"
the trick here is the units, get them common units,no mixed units.

5 2/12 ** x
------ = --------
**3*** ** 3 5/12
3 x = (31/6)(41/12)
x = 5.88 feet or 5 feet 10 1/2 inches
------ = --------
**3*** ** 3 5/12
3 x = (31/6)(41/12)
x = 5.88 feet or 5 feet 10 1/2 inches
Convert to inches, then use a ratio.
5'2' = 62"
3' = 36"
3'5" = 41"
62:36 = x:41
62/36 = x:41
Cross multiply and solve for x.
5'2' = 62"
3' = 36"
3'5" = 41"
62:36 = x:41
62/36 = x:41
Cross multiply and solve for x.
