c=leech=25 ft; a=height=24 ft; b=base
\n" ); document.write( " $\"b%5E2=c%5E2-a%5E2\"$
\n" ); document.write( " $\"b%5E2=%2826%5E2%29ft%5E2-%2824%5E2%29ft%5E2\"$
\n" ); document.write( " $\"b%5E2=%28676%29ft%5E2-%28576%29ft%5E2\"$
\n" ); document.write( " $\"b%5E2=%28100%29ft%5E2\"$ find square root of each side.
\n" ); document.write( " $\"b=sqrt%28100ft%5E2%29\"$
\n" ); document.write( "b=10 ft Base is 10 feet.
\n" ); document.write( "Area=1/2ba=1/2(10 feet)(24 feet)=120 sq ft The area of the sail is 120 sq ft.
\n" ); document.write( "120 sq ft($10/sq ft)=$1200 ANSWER: The cost of the sail is $1200.\r
