A triangle’s area is \(150\) square meters. Its height is \(15\) meters. Suppose we wanted to find how long is the triangle’s base. A triangle’s area formula is
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:
Check whether \(20\) is a solution for \(b\) of this equation.
