Yes simply with a protractor and a measuring device.
Simply because the Pythagorean Theorem is not true for any triangle that doesn't have a right angle in it. If a triangle has a right angle in it, then it satisfies the Theorem. If it hasn't, then it doesn't. And if it satisfies the Theorem, then it has a right angle in it, and if it doesn't, then it hasn't.
The Pythagorean theorem is actually the law of cos, where the angle is 90.

If you drive 9 miles north from your house, then turn and drive 12 miles east, you can use the Pythagorean theorem to calculate that you wind up 15 miles from home. You don't need a graph at all to do that. You just have to know the Pythagorean theorem.
The special case of the HL (Hypotenuse-Leg) theorem states that in a right triangle, if the hypotenuse and one leg of one right triangle are congruent to the hypotenuse and one leg of another right triangle, then the two triangles are congruent. This theorem is useful for proving the congruence of right triangles without needing to know the measures of the angles. It simplifies the process of triangle congruence by focusing on the right triangle's defining features.

Use the Pythagorean Theorem: a2 + b2 = c2
If you know the length of the sides but not the diagonal, you can use the Pythagorean Theorem.
no not really
If you know one side (s) and the opposite angle (a) then the hypotenuse = s/sin a...
Use trigonometry

It is not possible to answer the question without additional information about the triangle and the rectangle.
You find the height by using Pythagoras' theorem and then 0.5*base*height = area.
