No, the area of a triangle is half the base multiplied by the perpendicular height.
If the triangle has no perpendicular height, you can't use the length of a slanted side, watch out for that. Perpendicular lines meet like a capital T. At right angles.
Instead, you could use 1/2absinC
label each side of the triangle a,b and c.
label each corner with the same three letters but capitals.
label A the corner across from a
label B the corner across from b and so on.

multiply one half by the measures of a,b and sinC

When calculating the area of a triangle, you need to divide by 2 because the formula for the area of a triangle is 1/2 multiplied by the base multiplied by the height. This is because a triangle is essentially half of a rectangle, and the formula reflects this relationship. Dividing by 2 ensures that you are finding the correct area for the given triangle based on its base and height dimensions.
half base multiply height. 1/2BasexHeight
A triangle is half a square The area of a square is height × width(base) So, the area of a triangle is height × base ÷ 2 5×4÷2 = 10
The area of a triangle is half base times height. In this case the area is 20.3x5.6/2 =56.84mm^2
Half base x altitude...
