Plot the four points on a Cartesian coordinate plane and measure the length of the two diagonals. Length of one diagonal = |-3.5| + 3.5 = 7, and the length of the other diagonal = |-8| + 8 = 16.LUANDATO wrote:In a rectangular coordinate system, what is the area of a rhombus whose vertices have the coordinates (0, 3.5), (8, 0), (0, -3.5), (-8, 0)?

The area of the rhombus = Product of the diagonals/2 = (7*16)/2 = 56 sq unit
The correct answer: A
Hope this helps!

Here clearly length of digonals are 16 and 7
Therefore area = ½(16*7)= 56
Hence option A is correct
