The area of a rectangle is 36 square inches, the perimeter of the rectangle is 36 inches. What are the dimensions of the rectangle to the nearest hundredth of an inch?

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.

according to egenuity the answer is

step-by-step explanation:
