Exercise26

A triangle’s area is \(60\) square meters. Its height is \(12\) meters. Suppose we wanted to find how long is the triangle’s base. A triangle’s area formula is

\(\displaystyle{A=\frac{1}{2}bh}\text{,}\)

where \(A\) stands for area, \(b\) for base and \(h\) for height. If we let \(b\) be the triangle’s base, in meters, we can solve this problem using the equation:

\(\displaystyle{{60}=\frac{1}{2}(b)(12)}\text{.}\)

Check whether \(20\) is a solution for \(b\) of this equation.
