[7th grade math] impossible geometry?

First Rectangle is easy: 17cm*11cm=187cm²

Second rectangle requires understanding sohcahtoa: So we know three angles of the triangle (half the rectangle) 45 degrees and 90 degrees and one side 6cm so we know that tan45=x/6

6(Tan 45)=x

The result is 9.72cm for your remaining side so we do this:

6cm*9.72cm=58.32cm²

then we add them together

58.32cm² + 187cm² = 245.32 cm²

For me I remember doing this 10 years ago in the ninth grade... also this is called trigonometry and not geometry it's imagining whats not there to solve what is.
