find the area

In this problem, you are asked to solve the area of a trapezoid. The formula in finding the area of a trapezoid is:

A = [(a + b)/2] x h

Where a = base 1

             b = base 2

             h = height

Substituting the given measurements to the formula:

A = [(6.9 km + 2.7 km)/2] x 2.2 km

A = (9.6 km/2) x 2.2 km

A = 4.8 km x 2.2 km

A = 10.56 km^2

Therefore, the area is 10.56 square kilometers.

that would be a prism, if not right, feel free to correct me

c.

step-by-step explanation: it's not a. because 1/3 x 1/3 x 1/3 = 1/27 so that's not correct. | b. is also not correct because 7 x 7 1/3 is not actually 3 x 7 1/3 . and for d. multiplications are not additions so that left you with c. ( hope this out : d )
