The correct answer is D

Answer:

The answer is the option D

x=7, y=4

Step-by-step explanation:

we know that

If the triangles are congruent

then

The corresponding sides are congruent

AC=EF, BC=DE

substitute the values

5x-5y=2y+7 ------->5x=7y+7 --------> equation A

6y-8=2y+8 -------> 6y-2y=8+8 -------> y=4

Substitute the value of y in the equation A and solve for x

5x=7(4)+7

x=35/5

x=7

The two parallel bases b1 and b2 are
b1 = 12
b2 = 9
the order of which base you pick doesn't matter

The height is h = 10 and it's perpendicular to each base.

The area is...

A = (1/2)*h*(b1+b2)
A = (1/2)*10*(12+9)
A = (1/2)*10*(21)
A = 5*21
A = 105

Final Answer: B) 105 square centimeters
