Hello, I can help you lol.
\n" ); document.write( "


\n" ); document.write( "First let me give you the formula
\n" ); document.write( "A= (b1+b2)/2 X h OR A= 1/2h (b1+b2)
\n" ); document.write( "


\n" ); document.write( "i will use the second one ^^^
\n" ); document.write( "A= 1/2h (b1+b2)
\n" ); document.write( "


\n" ); document.write( "now plug in the Numbers:
\n" ); document.write( "84=1/2h(28)
\n" ); document.write( "


\n" ); document.write( "the next step is to multiply 28 by 1/2
\n" ); document.write( "28/2=14
\n" ); document.write( "


\n" ); document.write( "You are left with:
\n" ); document.write( "84=14h
\n" ); document.write( "


\n" ); document.write( "divide both sides of the equation by 14
\n" ); document.write( "


\n" ); document.write( "you get:
\n" ); document.write( "84/14=6
\n" ); document.write( "


\n" ); document.write( "So h=6
\n" ); document.write( "


\n" ); document.write( "to check the problem simply plug in the numbers:
\n" ); document.write( "84=1/2(6) (28) multiply 6*28=168
\n" ); document.write( "84=1/2(168)
\n" ); document.write( "84=84
\n" ); document.write( "
