Because they derive the formula from the area of a square. A square is width x height (or base x height). If you cut the square into two equal triangles, you can get the area of only a single triangle by dividing by 2.
It depends on what type of shape you are trying to find the area. If it is a rectangle, you do base times height. For triangles, you do base times height divided by two. For a circle, it is Pi*R^2.
The area of a triangle is (1/2) base times height; the height must be perpendicular to the base.The area of a triangle is (1/2) base times height; the height must be perpendicular to the base.The area of a triangle is (1/2) base times height; the height must be perpendicular to the base.The area of a triangle is (1/2) base times height; the height must be perpendicular to the base.
The area of a triangle is calculated using the formula A = 0.5 * base * height. Plugging in the given values, we get A = 0.5 * 14 cm * 6 cm = 42 square cm. Therefore, the area of the triangle is 42 square cm.
area of triangle: area equals base times height devided by two! a=bxh/2 a=40in b=20in THE ANSWER IS 4in as the height!
A triangle is a two-dimensional shape (flat), so it has area, but not volume. The area of a triangle is half the height times the base. Multiply the height times the length of the triangle's base, then divide by 2.
Area equals 1/2 of the base times the height.
Base times height divided by two EXAMPLE :: Area = base times height divided by 2 = 5cm times 2cm divided by 2 = 10 divided by 2 = 5 cm
Base times height divided by two EXAMPLE :: Area = base times height divided by 2 = 5cm times 2cm divided by 2 = 10 divided by 2 = 5 cm
Base times height divided by 2
base times height divided by 2
base times height then that divided by 2
base times height divided by 2
0.5*base*height. AKA base times height divided by 2
base times height. take that awnser and divide it by 2. bxh 2
base times height divided by 2
A= base times height divided by 2
base times height divided by 2.
