WebAny quadratic of the form ax^2 + bx + c can be solved using the formula ( -b +/- sqrt (D) )/2a with D= b^2-4*a*c. However, if D is less than zero it cannot be solved regularly. This requires the introduction if the imaginary number i = sqrt (-1). WebFeb 27, 2024 · Once you know the width and height of the triangle, put the numbers into the formula for calculating triangular area: [2] Area = 1/2 x width x height. You might also see it written as 3 Multiply 1/2 by width by height to get the area of the triangle.
