Yes because 5 + 4 is > 7

yeahhh...and more in details the area A will be equal to :

A =√(16/2)*(8-7)*(8-5)*(8-4) = √8*1*3*4 = √96

Yes, it's an obtuse triangle

if one side is five inches, a second side is seven inches and the third is four inches would make a scalene triangle.

4+5=9 > 7 yes 4,5,7 can be a triangle.

Yes, these can form a triangle.

By the triangle inequality rule, you need the two shortest sides (4 and 5) to add up to more than the longest side (7).

Since 4+5 > 7, we can say these would form a valid triangle.

Yes

Yes, these three numbers 7, 5, and 4, can be the measurements of the sides of a triangle.

Of course. Are you confusing a scalene triangle with a right, isosceles, or equilateral one?
