Algebra.Com's Answer #281610 by josmiceli(19441)![]() ![]() You can put this solution on YOUR website! A rhombus is a parallelogram with all 4 sides equal. \n" ); document.write( "The diagonals intersect at right angles, and they bisect each other. \n" ); document.write( "If you think of he rhombus as 2 triangles reflected about the \n" ); document.write( "7 cm diagonal, then the altitudes of these triangles are \n" ); document.write( "12/2 = 6 cm long. The area of 1 of these triangles is \n" ); document.write( "(1/2)x7*6 = 21 cm2 \n" ); document.write( "Twice this area 2 x 21 = 42 cm2 is the area of the rhombus \n" ); document.write( "Hope it's right \n" ); document.write( " |
