rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle A(2,-6),B(5,-6),C(5,-2),and D(2,-2). what is the area of rectangle ABCD?​

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

so what is the problem what are they asking you to solve
