\n" ); document.write( " $\"P=B%5B1%5D%2BB%5B2%5D%2BS%5B1%5D%2BS%5B2%5D\"$ Substitute $\"S%5B2%5D=S%5B1%5D\"$
\n" ); document.write( " $\"85in=10in%2B11in%2BS%5B1%5D%2BS%5B1%5D\"$ Subtract 21 inches from each side
\n" ); document.write( " $\"64in=2S%5B1%5D\"$ Divide each side by 2.
\n" ); document.write( " $\"32in=S%5B1%5D\"$ Side 1 is 32 inches.
\n" ); document.write( "ANSWER: Since the sides are equal, both sides are 32 inches \n" ); document.write( "
