Hi,
\n" ); document.write( "let the breath of the rectangle be \"b\"
\n" ); document.write( "then,
\n" ); document.write( "The length(L) = 3b-----(1)
\n" ); document.write( " Also,perimeter of a rectangle
\n" ); document.write( " 2(L+b)=96----(2)
\n" ); document.write( "substitute for L in equ (2) using equ (1)
\n" ); document.write( " 2(3b+b)=96
\n" ); document.write( " clear the bracket,
\n" ); document.write( " 6b+2b=96
\n" ); document.write( " 8b=96
\n" ); document.write( " divide bothside by 8
\n" ); document.write( " 8b/8=96/8
\n" ); document.write( " b=12
\n" ); document.write( "substitute for b in equ (1) L=3b
\n" ); document.write( "but b=12
\n" ); document.write( " then,
\n" ); document.write( " L=3*12
\n" ); document.write( " L=36
\n" ); document.write( "The length of the rectangle is 36m and breth is 12m
\n" ); document.write( " Area of rectangle(A)=L*b
\n" ); document.write( " =36m*12m =342m²
\n" ); document.write( "CHEERS,
