The area of a triangle is (base)x(height)x1/2.
So, we put in your values (base=19, height=14) and we get 19x14x1/2=19x7=133.
The area of a triangle with a base of 19cm and a height of 14cm is 133.

Area is 98cm2
Area = 1/2*14*15 = 105 square cm
I find the area by applying the standard formula for the area of a triangle, which is the length of the base multiplied by the height all divided by two. You should too.
To find the area of a triangle, you need the length of the base and the height. If the triangle has a base of 19 cm and a height of 21 cm, the area would be (1/2) * base * height = (1/2) * 19 cm * 21 cm = 199.5 cm^2. To find the perimeter of a triangle, you need to add the lengths of all three sides. Without knowing the lengths of the other sides, the perimeter cannot be determined.
Area of a triangle: 0.5*base*perpendicular height
