The formula in calculating the area of a triangle is A = 1/2 base * height while Perimeter = base + height + hypotenuse. From this example we are asking for a user input of base and height. The area can easily be calculated using direct substitution, however the perimeter would be harder since we ...Since the boundary of the triangle is made by three line segments which are its sides, the perimeter of the triangle is equal to the sum of all three sides. If there is a triangle whose side lengths are a, b, and c, the perimeter of the triangle is equal to, a + b + c. The perimeter of a ABC = sum of all three sides Hence, perimeter P = a + b + c Oct 28, 2021 · P = 3 x 6 = 18 cm Calculate the perimeter of an isosceles triangle On the other hand, isoscele triangles s are those in which two of its sides are equal and one different, which will be the base. Let P be the vector <r-k, s-m, t-n> and let Q be the vector <u-k, v-m, w-n>. The absolute value of the cross product of P and Q is given by the equation. where θ is the angle between P and Q. The right hand side is twice the formula for the area of a triangle. Thus, the area of the triangle formed by the three points is (1/2)|P × Q|. anime pics xa
