Question 1152442
{{{ 8 }}} in = {{{ 8/12 = 2/3 }}} feet
Let {{{ h }}} = height of building in feet
Use similar triangles:
{{{ h / 18 = 5.667 / 4 }}}
{{{ 4h = 5.667*18 }}}
{{{ 4h = 102 }}}
{{{ h = 25.5 }}} ft
---------------------
{{{ .5 }}} ft = {{{ .5*12 = 6 }}} in
The height of the building is 25 ft 6 in
