What is the perimeter of the figure to the nearest tenth of a millimeter
when the base is 6mm and the height is 3mm?

The answer would be 18mm because 6+6+3+3 considering that there are 4 sides.

Perimeter=2base+2height
Perimeter=2(6 mm)+2 (3 mm)=12 mm+6 mm=18 mm=18.0 mm

Solution 18.0 mm

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
