That would be an equilateral triangle.
It depends what kind of triangle it is. For example, it can be 20 by 20 by 5.
The figure is a triangle. That means it has 3 sides. The triangle is "equilateral". That means all three sides have the same length. One side is 5 cm. That means each of the other 2 sides is also 5 cm. So the perimeter is (5 + 5 + 5) = 15 cm.
There cannot be a "medium triangle with 5 sides". A triangle can have 3 sides and only 3 sides. Any other number of sides and it is not a triangle.
A triangle, by definition, has three sides. A polygon with five sides is called a pentagon.
If all the sides are equal to 5 cm, then it's a equilateral triangle. An equilateral triangle is a triangle in which all the sides are equal.
3, 4 and 5
That would be an equilateral triangle.
This is a right angle triangle.
1 triangle = 3 sides, no matter what kind of triangle it is 5 triangles = 3 sides each = 15 sides

An isosceles triangle has two sides of equal length.
The figure is a triangle. That means it has 3 sides. The triangle is "equilateral". That means all three sides have the same length. One side is 5 cm. That means each of the other 2 sides is also 5 cm. So the perimeter is (5 + 5 + 5) = 15 cm.
Area of a triangle is 1/2*Base*Height. I believe you can take it from here.
There cannot be a "medium triangle with 5 sides". A triangle can have 3 sides and only 3 sides. Any other number of sides and it is not a triangle.
No. A pentagon has 5 sides and a triangle has 3 sides.
A nonagon has 9 sides and a triangle has 3. So there are (5*9)+(1*3) = 48 sides in 5 nonagons and 1 triangle.
