The side of a rhombus is 28 m and length of one of its diagonals is 12 m. The area of the rhombus is?	Pick one:
A) 326.2 B) 324.2 C) 328.2 D) 338.2 E) 328.9
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 : 328.2
