Don and Ron were arguing about how to write the equation to find the area of the shaded region in the figure below. Don says the equation must be
A 10(12) 7(2) = −
. Ron says the equation must be
A 7(2) 12(10) = −
. Who is correct? Explain why he is correct.

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
