LAB ACTIVITY

$7\mathrm{.}47\mathrm{.}1$: LAB: Triangle area comparison $($classes$)$

Given class Triangle $($in files Triangle.h and Triangle.cpp$),$ complete main$()$ to read and set the base and height of triangle$1$ and of triangle$2,$ determine which triangle's area is smaller, and output that triangle's info, making use of Triangle's relevant member functions.

Ex: If the input is:

$\backslash [$

$\backslash$begin$\{$array$\}\{$ll$\}$

$3\mathrm{.}0$ & $4\mathrm{.}0\backslash \backslash$

$4\mathrm{.}0$ & $5\mathrm{.}0$

$\backslash$end$\{$array$\}$

$\backslash ]$

where $3\mathrm{.}0$ is triangle$1\text{'}$s base, $4\mathrm{.}0$ is triangle$1\text{'}$s height, $4\mathrm{.}0$ is triangle$2\text{'}$s base, and $5\mathrm{.}0$ is triangle$2\text{'}$s height, the output is:

$```$

Triangle with smaller area:

Base: $3\mathrm{.}00$

Height: $4\mathrm{.}00$

Area: $6\mathrm{.}00$
