You can put this solution on YOUR website!
One wall's area = (length)*(height) = 10*4 = 40 square meters\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The parallel wall on the opposite side is also 40 square meters\r
\n" ); document.write( "\n" ); document.write( "----------------------------------------------------------------\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Other wall's area = (breadth)*(height) = 5*4 = 20 square meters\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The parallel wall on the opposite side is also 20 square meters\r
\n" ); document.write( "\n" ); document.write( "----------------------------------------------------------------\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Add the areas: 40+40+20+20 = 120\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So that's why the answer is 120 square meters \n" ); document.write( "
