Now we will hold these figures, The scale factor is the ratio of alength of the image to the corresponding length on the original figure. Substituting h into the first area formula, we obtain the equation for the equilateral triangle area: Let's start with the trigonometric triangle area formula: area = (1/2) a b sin(), where is the angle between the sides. Obviously using both a tangent calculator and an exponent calculator is quite helpful. There are various ways in which we can present the scale: Numerical scale It's dimensionless, and the form 1:1000 denotes that the scale factor equals 0.001. We often stick to some of the commonly used architectural scales in construction or landscaping projects. Enlargement - what do I need to know?
