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.
I don't know about the relation in the perimeters of a triangle and a parallelogram but if a triangle is on the same base on which the parallelogram is and the triangle is between the same parallel lines of the parallelogram, then the area of the triangle will be half the area of the parallelogram. That is, area of a triangle = 1/2 area of a parallelogram if the triangle is on the same base and between the same parallel lines.
I'm assuming that you mean the area of the triangle. You do not need the entire perimeter. The formula is 1/2 bh. b=base, h=hight
If the base of a triangle is b and the height of the triangle is h, the area of the triangle is given by the formula: area = 0.5 x b x h.As such, in your case we have 28 = 0.5 x 4 x h, which means that h = 14.
Lengths of: equal side+equal side+base = perimeter
1/2 base x height
It is: perimeter minus hypotenus+base = height Area = 0.5*base*height
The base is one third of the perimeter, half of the base times the height is the area.
Area of a triangle in square units = 0.5*base*height
The area of a triangle is the base length multiplied by the height divided by two.A = b*h/2The perimeter of the triangle is the sum of all of the side lengths.P = side1 + side2 + side3
Area:A=1/2bhA=Area b=Base h=HeightPerimeter:P=a+b+cP=Perimeter a,b,c=side lengths of the triangle
You multiply the base and the height and then you divide the answers of that by 2. :)
to find the area of a triangle you divide the base of the triangle by two and multiply your answer by the height .so your formula would be 1/2b times h to find the perimeter of a triangle u simply just add the sides.
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 height of the triangle and using the formula: 1/2*base*height = area
The relation between the height of a triangle, its base and its area is given by: Area = 0.5 * Base * Height Therefore, we have: Height = (2 * Area)/ Base.
Divide the area by height then you get the base.
The perimeter of an object is simply the length of its border, so the perimeter of a triangle is the sum of the lengths of its 3 sides.The area of a triangle is equal to half of its base times its height, for example if a triangle had a base of length 4 and was 5 units tall, it would have an area of (4*5)/2, or 10 units2.
