The length of a rectangle is twice that of its breadth. If the length of the rectangle is decreased by 10% while its breath increase by 10% determine, if any, the percentage change in its perimeter​

For the first question the answer is a, for the second c, for the third d, for the 4th b, for the 5th a

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
