If the perimeter of the rectangle is 64m, find its area \n" ); document.write( "W=width; L=length=3W; P=perimeter=2(L+W) \n" ); document.write( "P=2(L+W) \n" ); document.write( "64m=2(L+W) Divide each side by 2. \n" ); document.write( "32 m=L+W Substitute for L. \n" ); document.write( "32 m=3W+W \n" ); document.write( "32m=4W Divide each side by 4. \n" ); document.write( "8m=W The width is 8 meters. \n" ); document.write( "L=3W=3(8 m)=24 m The length is 24 meters. \n" ); document.write( "A=L*W=24 m*8 m=192 sq m ANSWER: The area is 192 square meters. \n" ); document.write( " |
