Let $\"+w+\"$ = the width of the tank
\n" ); document.write( " $\"+15%2A27%2Aw+=+405w+\"$ m3 is the capacity of the tank
\n" ); document.write( " $\"+405w+-+450+=+15%2A%28+27+-+3+%29%2Aw+\"$
\n" ); document.write( " $\"+405w+-+450+=+15%2A24%2Aw+\"$
\n" ); document.write( " $\"+405w+-+450+=+360w+\"$
\n" ); document.write( " $\"+45w+=+450+\"$
\n" ); document.write( " $\"+w+=+10+\"$
\n" ); document.write( " $\"+405w+=+4050+\"$
\n" ); document.write( "The breadth is 10 m
\n" ); document.write( "The capacity is 4050 m3
\n" ); document.write( "-------------------------
\n" ); document.write( "check answer:
\n" ); document.write( "The amount left after drawing off $\"+450+\"$ m3 is:
\n" ); document.write( " $\"+4050+-+450+=+3600+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+15%2A24%2Aw+=+15%2A24%2A10+\"$
\n" ); document.write( " $\"+15%2A24%2A10+=+3600+\"$
\n" ); document.write( "OK\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
