How do you find the area and perimeter of a triangle?
Area:A=1/2bhA=Area b=Base h=HeightPerimeter:P=a+b+cP=Perimeter a,b,c=side lengths of the triangle
How do you find the perimeter of a triangle if you know the area?
You cannot. For a given area, an equilateral triangle will have the smallest perimeter but that perimeter can be increased - without limit - without increasing the area.
How do you find the perimeter of a triangle when only the base and area are given?
A = 1/2bh then you use Pythagoras theorem to find the length of the other 2 sides, using the known value for the height and 1/2 of the bases value.
How do you find the perimeter of a triangle when the perimeter is 177?
If you know the perimeter, there is no need to find it again.
How do you find the area of a triangle given only the perimeter?
It is possible depending on what type of triangle it is.For instance if it was an equilateral triangle then all sides would be equal and then by means of Pythagoras' theorem you could work out the...
