The formula for a trapezoid relates the area a, the two bases, a and b, and the height, h a=h(a+b)/2 solve for b. a. b=ah/2-a b. b=2a/h+a c. b=2a/h-a d. b=2a-a/h

Given that the formula for a trapezoid that relates the area A, the two bases, a and b, and the height, h is given by:



To solve for b, first multiply both sides by 2 to get:

2A = h(a + b) = ah + bh

Next, subtract ah from both sides to get:

2A - ah = bh

Next, divide both sides by h, to get:

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
