No, because you need some length for the third side - two lengths will only give an angle between them.
If the third side is greater than 3 ft and less than 13 ft then you can make a triangle with it, 8 ft and 5 ft.
It is square ft.
18 ft
Yes, the three given lengths will form a triangle. Three lengths can make a triangle if, and only if, the sum of the two shorter lengths is greater than the longest length. The two shorter lengths are 56 ft and 16 ft with a sum of 56 ft + 16 ft = 72 ft 72 ft is greater than 65 ft so 56 ft, 65 ft and 16 ft will make a triangle.

The ratio of the length of the side of a right angle triangle must be 3,4,5 16,56,65 are not in that ratio.
No
No it is not. To be a right triangle the largest number squared has to equal the sum of the squares of the other two sides (Pythagorean theorem).
yes
If 35 ft and 80 ft are two sides of the triangle, the third side must be more than 45 ft and less than 115 ft. So the perimeter is between 160 and 230 ft.
Draw a square with sides of 20.87 ft.
Area of a triangle = (base x Height)/2 = 7 ft x 15 ft/2 = 105/2 sq ft= 52.5 sq ft
