Rectangle A is 0.7x+1 cm long and 1.5x-2 cm wide.
\n" ); document.write( "Rectangle B is 2.5+x long and 4-1.3x wide.
\n" ); document.write( "The two rectangles have equal perimeters.
\n" ); document.write( "What are the dimensions of each rectangle?
\n" ); document.write( ":
\n" ); document.write( "if the perimeters are equal the sum of the lengths and widths are equal
\n" ); document.write( ".7x + 1 + 1.5x -2 = 2.5 + x + 4 - 1.3x
\n" ); document.write( "Combine like terms
\n" ); document.write( ".7x + 1.5x - x + 1.3x = 2.5 + 4 - 1 + 2
\n" ); document.write( "2.5x = 7.5
\n" ); document.write( "x = 7.5/2.5
\n" ); document.write( "x = 3
\n" ); document.write( "First rectangle
\n" ); document.write( ".7(3) + 1 = 3.1 cm
\n" ); document.write( " by
\n" ); document.write( " 1.5(3) - 2 = 2.5 cm
\n" ); document.write( "2nd rectangle
\n" ); document.write( "2.5 + 3 = 5.5 cm
\n" ); document.write( "by
\n" ); document.write( " 4 - 1.3(3) = .1 cm
\n" ); document.write( ":
\n" ); document.write( "you can check the perimeters of both, ensure they are equal \n" ); document.write( "
\n" );
