#38 cm -=1.246875" feet" larr" exact value"#

#38cm~~ 1"foot " 2" inches "61/64ths larr" approximate"#

1 mitre is 3 feet 3 inches and 3/8 of an inch

Converting this to decimal

#3/8" inch" = 0.375" inches"#

#3 + 3/8" inches "= 3.375" inches"#

But there are 12 inches in a foot so

#3 3/8 " "-= 3.375xx1/12 = 0.28125" feet"#

So #color(blue)("1 metre " -=" " 3" feet "3color(white)(.) 3/8" inches" color(blue)(->3.28125 " feet")#
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

There are 100 cm in 1 mitre so 38 cm #=38/100# of 1 metre

Thus, as feet, #38 cm = 38/100xx3.28125" feet"#

#38 cm -=1.246875" feet" larr" exact value"#
