base and height are read from input as floating$-$point values, representing the base and height of a triangle. Compute the triangle's area as $($base$*$height$)/2.$ Use f$-$string's $=$ sign feature within the provided curly brackets as the replacement field to output both the expression and result.

Note: print $(f^{\text{'}}\{2**4={\}}^{\text{'}})$ outputs the string $"2**4=8"$ using $f-$string's $=$ sign feature.
