Answer:
approximately 6.708 feet
Step-by-step explanation:
We use the Pythagorean theorem to solve the problem, using 3 feet and 6 feet as the legs of a right angle triangle. The diagonal of the screen is therefore the "hypotenuse" of this right angle triangle, and can be determined via the formula:
![diagonal = \sqrt{(3\,ft)^2+(6\,ft)^2} \\diagonal = \sqrt{9\,ft^2+36\,ft^2} \\diagonal = \sqrt{45} \,ft\\diagonal = 3\,\sqrt{5} \,ft](https://tex.z-dn.net/?f=diagonal%20%3D%20%5Csqrt%7B%283%5C%2Cft%29%5E2%2B%286%5C%2Cft%29%5E2%7D%20%5C%5Cdiagonal%20%3D%20%5Csqrt%7B9%5C%2Cft%5E2%2B36%5C%2Cft%5E2%7D%20%5C%5Cdiagonal%20%3D%20%5Csqrt%7B45%7D%20%5C%2Cft%5C%5Cdiagonal%20%3D%203%5C%2C%5Csqrt%7B5%7D%20%5C%2Cft)
which is approximately 6.708 feet
