The base of a triangle is almost always the side it lays on.
Just find the length.
If you're looking for how to solve it with algebra, given: Area=30 and Height=4
Remember: Area of a triangle = 1/2 (base ) x (height)
Then write the equation: 30 = 1/2 (base) x (4)
To solve it, divide each side by 2 :
15 = (base)

How do you find aras of triangles and parallelograms?
Triangles you use : (base x perpendicular height) divided by 2. Parallelogram: you need to find the area of one of the side triangles, then double it (because there's two of them). Then find the area of the square in the middle, and add this to the area of the two triangles.
How do you find the area of triangles?
area = 1/2 base x height
How do you find the area of the triangles if you only have the base and the height?
area =1/2 base length x height
How do you find right triangles altitutde?
If you know the hypotenuse and the base then use Pythagoras' theorem to find the altitude
How do you find surface area of an equilateral triangles?
Area = 0.5*base*perpendicular height
How many triangles dose it have in a square base pyaridmed?
In a pyramid, all the faces that go from the base to meet at the apex are triangles, one on each side of the base. For a square base pyramid, there are 4 sides to the base, so there are 4 triangles Be careful with a triangular based pyramid, there are 3 triangles from the base to the apex, but there is also the triangle of the base itself, so there are 4 triangles in a triangular based pyramid.
Find the area of an isosceles triangle?
For all triangles: area = 1/2 * base * height

What is the formula for a triangular pyramid in surface area?
A=1/2bh The area of a triangle is 1/2bh. If the base of it is a triangle and all 4 of the triangles aren't the same, then you have to find the area of the base triangle and then the three other triangles (which should all have the same area). If all four of the triangles have the same area, then just find the area of one of the triangles and multiply that by four. A triangular pyramid that has four equal triangles is also called a tetrahedron.
Are two triangles congruent if they have same area?
Not necessarily. You find the area of a triangle with the formula 1/2*base*height=Area. Imagine two triangles, one with 3 inches for both the base and height, and one with 4.5 inches for the height and 2 inches for the base. Both of these triangles will have 9 sq. in. for their areas, but they are not congruent.
What is the formula to find the area of an isosceles triangle?
For all triangles: area = 1/2 * base * height
How you find the area with only the base for the triangle?
No. You can have a million triangles, all with the same base but different areas. Just the base alone is not enough information to tell you what the area has to be.
