{{{W=7 yd +2ft=21ft+2ft=23ft}}}  
{{{L=12yd +1ft=36ft+1ft=37ft}}}  


a... Find the perimeter of the cellar in feet

the perimeter {{{P=2(W+L)}}}

{{{P=2(23ft+37ft)}}}

{{{P=2(60ft)}}}

{{{P=120ft}}}

b...If the perimeter(edge) of the cellar floor needs to be sealed
with waterproof sealer that costs $1.75 per foot, how
