A home is to be built on a 56 foot 9 inch wide lot. The house is 5 feet 5 inches from the side of the lot and is 34 feet 10 inch

Anni [7]

Check the picture below, so the distance of the house from the other side is that blue gap.

so, there are 12 inches in 1 foot, so let's just convert all those feet to inches and subtract them.

$\bf 56'\implies (56\cdot 12)''\implies 672''
\\\\\\
5'5''\implies (5\cdot 12+5)''\implies 65''
\\\\\\
34'10''\implies (34\cdot 12 + 10)''\implies 418''\\\\
-------------------------------\\\\
672''-(65+418)''\implies 189''\implies 15'9''$
