The formula for finding the area of a triangle is half of the base x the height. For this triangle, it would be 1/2 of 10 X 3, or 15 square units.
The Formula is Base*Height, or 1/2 Height (altitude of the triangle) * Base (of the Triangle) * height (Height of the prism)
the formula is 1side multiply by 3
Area=1/2(base*height) where either side can be the base or the height in a right triangle.
To find the volume, you first find the area of the triangle base and then multiply it be the height.
Area of a triangle: 0.5*base*perpendicular height
length times width times height
The area of any triangle is1/2 of (the length of the triangle's base) times (the triangle's height).
we dont know
You multiply the base and the height and then you divide the answers of that by 2. :)
1/2 the base times height or 1/2 the height times base
The formula for the area of a triangle is base times height, divided by 2. The base is one of the sides and the height is a perpendicular line connecting the base to its opposite point.
the formula for finding the area of a triangle is 1/2base * height. so 1/2(6.2) * 4.5 = 13.95 in2
The formula for finding the area of a triangle is base multiplied by height divided by two(B*H/2)Made by: Christine Ayoh
Volume = Area of the base X height of prism. This formula works for all prisms, not just triangular prisms. Area of a triangle = height of triangle X 1/2 X base of triangle.
The formula is A=1/2bh b=base of triangle h=height of triangle A=area 1/2=divide base times height by 2
The formula for finding the area of a triangle is: Area = 1/2*height*base in square units. Therfore substituting the values into the formula we have: 70 = 1/2*height*7 Rearranging the formula to find the height gives us: height = 70*2/7 = 20 inches. Therefore the height of the triangle is 20 inches.
