Answer:

16 square units

Explanation:

You want to know the area of rhombus ABCD whose vertices are ...

  • D(-5,2)
  • C(-1,0)
  • B(3,2)
  • A(-1,4)

Area formula

The area of a rhombus can be found using the formula ...

A = 1/2ab . . . . . where 'a' and 'b' are the lengths of the diagonals

Application

The diagonals of this rhombus are horizontal and vertical lines, so their lengths are easily found.

Diagonal AC is 4 - 0 = 4 units long.

Diagonal BD is 3 -(-5) = 8 units long.

Then the area is ...

A = 1/2(4)(8) = 16 . . . . square units

The area of rhombus ABCD is 16 square units.
