Corey drew a sketch of a paper hat

If a = 4 in and b = 3 in, what is the area of the sketch?
A.
84 in2
B.
60 in2
C.
40 in2
D.
21.5 in

Not on there but it is 76in2

Step-by-step explanation:

Starting with the trapezoid. We know that a trapezoid can be split into 2 triangles and 1 rectangle. So the area of the trapezoid will be 4+32+4 which is 40 now that we know the trapezoid's area we can find the rectangle's area. The rectangle's area will be 12x3 which is 36. So, you would add both:40+36= 76in2.
