Trapezoid will consist of a rectangle with breadth = 9m (height of trapezoid) \n" ); document.write( "and two right traingles one of side of each will be teh height of trapezoid viz 9m and the base add upto 18m(25m (one side fo tapezoid)-7m(the other side)) \n" ); document.write( "Hence area of trapezoid = area of two triangles +area of rectangle \n" ); document.write( " =1/2 * base* height +1/2 * base* height + 9*7 \n" ); document.write( " =(1/2*9)(base+base) +63 \n" ); document.write( " =81 +63 \n" ); document.write( " = 144 sq m\r \n" ); document.write( "\n" ); document.write( "Perimter = sum of all sides = 2(6.5+3) m = 19m\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( " |
