To get the area it half breadth by height. A simplified thought on this is because the formula for the area of a parallelogram is length by width, and a triangle would be half of this

The answer to the problem 1.5 multiplied by -6 is -3.   one half multiplied by five eighths... 0.5 * 0.635 = 0.3175 OR 1/2 * 5/8 = 5/16 The formula to calculate the area of any triangle is half the length of the base, multiplied by the height. Therefore in this case it's 32.76 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. find the sin of C using your calculator multiply one half by the measures of a,b and sinC  Five sixths multiplied by two and one half is about 2.083.     one half multiplied by one half or 1/2 x 1/2 = 1/4   One half multiplied by two-thirds is two-sixths and if you reduce it would be one-third. A triangle is a 2 dimensional object, it cannot therefore have a volume (which is a property of 3D objects.However, if you meant area, then it's half the base length multiplied by the height.
