Is this correct?? Please dont mine the little notes I took when solving it.. A= 12, base= 16

Area= (1/2)(12)(16) = 96

384+96 =480

Semi Circle should be something like =(1/2) pir^2

diameter= hypotenuse= sqrt(12^2 +16^2) = 20

radius= r= d/2= 20/2

Semi Circle= (1/2) pi 10^2= 50pi= 157.0796327

Total = 480+157.0796327=637.0796327. Rounding to the nearest hundred would give me 637.08??

care to share were the trapezoid shown is ?

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
