Geometry: Common Core (15th Edition)

$AC$ = $9$ $m^2$ $CB$ = $16$ $m^2$ $BA$ = $25$ $m^2$
First side: $AC$ = $($3$m)^2$ Square both the value and the unit: $AC$ = $9$ $m^2$ Second side: $CB$ = $($4$m)^2$ Square both the value and the unit: $CB$ = $16$ $m^2$ Third side: $BA$ = $($5$m)^2$ Square both the value and the unit: $BA$ = $25$ $m^2$
