From a rectangle , corner is cut in triangular shape to give a pentagon .
\n" ); document.write( " The length of the sides are 13,19,20,25 and 31 in cm . lengths are not in order
\n" ); document.write( " . find the area of the pentagon.
\n" ); document.write( ":
\n" ); document.write( "I assigned the dimensions as follow:
\n" ); document.write( "starting with the hypotenuse of the triangle = 13
\n" ); document.write( "the remaining part of that side = 19
\n" ); document.write( "bottom = 25
\n" ); document.write( "vert side = 31
\n" ); document.write( "top = 20
\n" ); document.write( ":
\n" ); document.write( "Find the area of the rectangle without the triangle removed
\n" ); document.write( "25 * 31 = 775
\n" ); document.write( ":
\n" ); document.write( "The triangle dimensions: 5 by 12 by 13,
\n" ); document.write( "prove it is a right triangle: \"sqrt%285%5E2%2B12%5E2%29\" = 13
\n" ); document.write( "A = .5 * 5 * 12 = 30
\n" ); document.write( ":
\n" ); document.write( "Pentagon area: 775 - 30 = 745
\n" ); document.write( "
\n" );
