Given A=1/2(bh), solve for h.

Question

Can someone tell me what this means, please?

 

Answer 1

A = (1/2)bh   is a very well-known formula.  It is for the Area of a triangle.

         A = area of the triangle

         b = length of base

         h = height

 

Note: Such a triangle is half (that is, 1/2) the area of a rectangle with the same base and height lengths.

 

To "solve" means to find the values of a variable for which this equation is true.  When you have multiple variables, to solve for h just means to get h alone on the left side and some expression on the right side of the equals sign.

 

    A = (1/2)bh

    2A = bh

    2A/b = h

    h = 2A/b             [use this formula to find h when you know A and b]
