For it to be a right angle triangle the 3rd side must be 5cm
Mean = sum(X)/n = 15cm/5 = 3cm
You cannot, because you have no information on the shape: is it a 2-d triangle or a 3-d cuboid?

16 cm 5cm+5cm+3cm+3cm=16cm
15 cm
It is 94 square centimetres.
Area of trapezoid: 0.5*(5+3)*3 = 12 square cm
The triangle with side lengths of 3cm, 5cm, and 3cm is classified as a scalene triangle. A scalene triangle is a triangle in which all three sides have different lengths. In this case, the three sides have lengths of 3cm, 5cm, and 3cm, making it impossible for the triangle to have any congruent sides or angles.
