Find the area of the parallelogram with vertices at...? (-6,-4), (0,-4), (3,4), and (-3,4)

A) 14
B) 48
C) 24
D)

• MATH -

Procedure: Calculate 1 hor side and the height. A = bh.

A(-6,-4), D(0,-4). AD is a hor. side.

A(-6,-4), B(-3,4). AB is a slant line.
tanA = Y/X = (4-(-4)) / (-3-(-6) = 8/3.
Y = 8 = h.

Area = bh = 6 * 8 = 48.
