I wish i was smarter too... Triangles DEF and D′E′F′ are shown on the coordinate plane below:

What rotation was applied to triangle DEF to create triangle D′E′F′?

90° clockwise
180°
None of the above
90° counterclockwise

I believe the answer is 180°

rectangle: 9 1/8 x 4 1/9 = 37 37/72in

parallelogram: b times h= 10.3 x 6.2 = 63.86

trapezoid: a+b/2 times h= 42.5

volume of prism: l times w times h= 36
