The area of a parallelogram is calculated by multiplying base length times height.
\n" ); document.write( "The area of a parallelogram with a base length of 3 feet and a height of 7 feet is
\n" ); document.write( "\"Area=%283feet%29%2A%287feet%29=+21\" \"square\"\"+feet\"
\n" ); document.write( "The surface area of a prism is calculated by adding the base surface area times two (for the 2, bottom and top, bases), plus the surface area of the sides.
\n" ); document.write( "The surface area of the sides can be calculated by multiplying the perimeter of the base times the height of the prism. That is the area of a rectangle that would wrap all around the sides of the prism.
\n" ); document.write( "The perimeter, P, of a rectangle is the sum of the length of all the sides. You could add length, l, and width, w, different ways:
\n" ); document.write( "\"P=l%2Bw%2Bl%2Bw\" or
\n" ); document.write( "\"P=2%2Al%2B2%2Aw\" or
\n" ); document.write( "\"P=2%28l%2Bw%29\"
\n" ); document.write( "The perimeter of a rectangular base that is 4 x 8 is
\n" ); document.write( "\"P=2%2A4%2B2%2A8=8%2B16=24\"
\n" ); document.write( "The lateral surface area (surface area of the sides) of a rectangular prism with a base that is 4 x 8 and a height that is 5 is
\n" ); document.write( "\"Lateral\" \"Area=24%2A5=120\"
\n" ); document.write( "The surface area of a base that is 4 x 8 is
\n" ); document.write( "\"Base\" \"Area=4%2A8=32\"
\n" ); document.write( "The total surface area of a rectangular prism with a base that is 4 x 8 and a height that is 5 is
\n" ); document.write( "\"Total\" \"Area=2%2A32%2B120=64%2B120=184\"
