Explanation Formula used: Area of the equilateral triangle, A = 1 2 × base × height . Calculation : Let the side length of the equilateral triangle be x. Obtain the height of the equilateral triangle as follows: Draw a line from any vertex to its opposite side so that it makes two equal right angled triangles. Consider any one of the right angled triangle. Since the side of the equilateral triangle is x , the base of the right angled triangle is x 2 . Let the height of the right angled triangle be h . Note that the height of the right angled triangle is the height of the equilateral triangle. Apply Pythagoras theorem and obtain the value of height. ( x 2 ) 2 + h 2 = x 2 x 2 4 + h 2 =

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
