the side of a rhombus is 28 m and length of one of its diagonals is 12 m . the area of the rhombus is ?
"area of the rhombus = 1 / 2 * p * √ 4 ( a ) 2 - ( p ) 2 a = 28 ; p = 12 a = 1 / 2 * 12 * √ 4 ( 28 ) 2 - ( 12 ) 2 = 1 / 2 * 12 * √ 3136 - 144 = 1 / 2 * 12 * √ 2992 a = 328.2 answer : c"
divide(multiply(12, sqrt(subtract(power(multiply(const_2, 28), const_2), power(12, const_2)))), const_2)
