Evaluating Formula

One of the most important applications of algebraAlgebra is a branch of mathematics that substitutes letters for numbers. Algebra is about finding the unknown or putting real-life variables into equations and then solving them. More is in the use of formula.

A formula is simply an equation which describes the relationship between two or more quantities. 

Let A = \(\frac{1}{2} \scriptsize (a + b )h\! \!\), where “a” and “b” are the parallel sides and “h” is the perpendicular distance between the parallel sides.

In this case, A ...
