A triangle with those measurements would just form a straight line.

V = 1693.32 cm3

The height has not been given but the area of the triangle is: 0.5*height*base

56 cm2 * * * * * Only if these are the shorter legs of a right angled triangle and there is no justification for making that assumption. Two sides of a triangle are not sufficient to determine its area.

Yes because the given dimensions complies with Pythagoras' theorem for a right angle triangle.

If two sides of a triangle have lengths of 5cm and 12cm, then the third side can have any length that's more than 7cm and less than 17cm. If the third side is 13cm, then the triangle is a right triangle.

77cm. That should've been quite obvious.... all you do is multiply 7 by 11 and BAM, you have 77!

Yes, if we consider 41 cm is the approximation of 40.608 cm.

No.

The area of triangle is : 42.0
