PLS HELP Find the area of the shaded region. PLEASE

Reason:

The parallelogram has area of A = base*height = 10*7 = 70 cm^2

The white rectangle has area of B = base*height = 3*2 = 6 cm^2

The shaded region has area of A - B = 70 - 6 = 64 cm^2

If you are curious why the rectangle and parallelogram use the same formula to get the area, notice how you can move that triangle on the left toward the right side so that a rectangle can be formed.

Answers:

B.The corresponding angles of the triangles are congruent

D.The image is a reduction of the pre-image

E. Neither the dilation nor the rotation change the shape of the triangle
