The answer depends on what information you have and what level of mathematics you have reached.
If you have three sides, a, b and c, then let s = (a + b + c)/2 Area = sqrt[s*(s - a)*(s - b)*(s - c)]
Two sides and included angle, a, b and C Area = 1/2*a*b*sin(C)
Two sides and non-included angle, a, b and A (or B) use the sine rule to find the angle opposite the other known side. Use the sum of the angles of the triangle to find the included angle. Then as in previous case.
One side and two angles, a, B and C Since the sum of the angles is 180 you effectively know all 3 angles. Use the sine rule to work out another side and then use the rule for a, b and C.
Equilateral triangle, sides a then Area = [sqrt(3)*a^2]/4
Base, b and height, h: Area = 1/2*b*h
There are other formulae.

What is the area of a triangle with a base of 7 inches and height of 6 inches?
The area of a triangle is calculated using the formula: Area = 1/2 * base * height. Substituting the values given, the area of the triangle would be: 1/2 * 7 inches * 6 inches = 21 square inches.
What is the formula for a triangles area?

How can you make the height of the flame smaller on a Bunsen burner?
To make the height of the flame smaller on a Bunsen burner, you can adjust the air hole at the base of the burner. By opening the air hole slightly, less oxygen will reach the flame, leading to a smaller and more controlled flame height.
What is formula pyramid for density?
There are some formulas for pyramids for area and perimeter. There is also one if you have a 2D pyramid that has, lets say blocks for the base. 0 00 000 0000 Like that. There is a formula without the E, to find out how many 0's there are in the pyramid. Total num.=((base num./2)+0.5)base num. T=((n/2)+0.5)n In this case the base num. is 4 because there are 4 0's on the bottom of the pyramid. T=((4/2)+0.5)4 T=(2+0.5)4 T=(2.5)4 T=10 There are ten 0's in the above pyramid. The area is base * height /2 a the perimeter is all the sides added together.
What is the symbol and element for ''sea water?
The symbol for sea water is H2O, which represents water. Sea water is primarily composed of water (H2O) and contains dissolved salts, such as sodium chloride (NaCl), magnesium chloride (MgCl2), and others.
How do you find the area and perimiter of a triangle?
To find the area of a triangle find the base and the height of the triangle. Then multiply the base by the height, then divide by 2. To find the perimiter of a triangle add together the outside edge of the triangle. To find the area of a triangle find the base and the height of the triangle. Then multiply the base by the height, then divide by 2. To find the perimiter of a triangle add together the outside edge of the triangle.
What is the height of a triangle when its the base is 10cm?
It is impossible to find the height of a triangle with just it's base.
How do you find the area of a triangle if you have base and height?
Area = 0.5*Base*Height
How do you get the height of a triangle?
To find the height of a triangle you measure it. It has to be from the middle of the base to the top point.
How can you find the height of a triangle if you have base and 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.
How do you find base of triangle when you have height?

How do you find the base and height of an isosceles triangle?
An isosceles triangle has 2 equal base angles and its height is perpendicular from its apex to the centre of its base
How do you find the base of a triangle if you only have the height and the area?
base = (2*area)/height
How do you find the base of a triangle with the area and height?
It is found by: base = (area*2)/height
How do you find the area of a triangle when you have the base and height?
Area = 1/2 * base * height.
How do you find the base of a triangle if the height and area are given?
Divide the area by height then you get the base.
