The lateral area and total area would require knowing the size of that square base.
\n" ); document.write( "The problem does not provide that information directly,
\n" ); document.write( "but the length, \"s\" , of the base sides
\n" ); document.write( "can be calculated from the information given.
\n" ); document.write( "A top view, and a cross section of the pyramid
\n" ); document.write( "(cutting across the middle of opposite lateral faces)
\n" ); document.write( "would look like square and the isosceles triangle below
\n" ); document.write( " Applying the Pythagorean theorem to right triangle ABC,
\n" ); document.write( "\"%28s%2F2%29%5E2%2B24%5E2=25%5E2\" --> \"%28s%2F2%29%5E2%2B576=625\" --> \"%28s%2F2%29%5E2=625-576\" --> \"%28s%2F2%29%5E2=49\" --> \"s%2F2=7\" --> \"s=14\" .
\n" ); document.write( "The \"4\" lateral faces are triangles with base \"s=14\" and height \"25\" ,
\n" ); document.write( "so the lateral area is
\n" ); document.write( "\"4%2A%2814%2A25%2F2%29=highlight%28700%29\" square units
\n" ); document.write( "(of whatever units was used to measure pyramid height and slant height).
\n" ); document.write( "The area of the square base is \"14%5E2=196\" square units,
\n" ); document.write( "so the total area (in square units) is
\n" ); document.write( "\"700%2B196=highlight%28896%29\" square units.
\n" ); document.write( "
\n" );
