A 9 x 12 rectangle has a diagonal of 15.
To find the corner-to-corner measurement (diagonal) of a 20' x 40' rectangle, you can use the Pythagorean theorem. The diagonal ( d ) is calculated as ( d = \sqrt{(20^2 + 40^2)} ). This results in ( d = \sqrt{(400 + 1600)} = \sqrt{2000} ), which simplifies to approximately 44.72 feet.
The diagonal multiplied by sin(angle) gives one side of the rectangle and the diagonal times cos(theta) gives the other. So the area is (diagonal)2 x cos(theta) x sin(theta).
sqrt 3200 =sqrt 100 x sqrt 16 x sqrt 2 = 40 root 2 = approx 56.5
