Answer:
Area of a trapezoid = ½(a + b)h, where a and b are the lengths of the parallel sides and h is its height.
From your information 20 = ½(2z + 3 + 6z – 1)z = ½(8z + 2)z = z(4z + 1)
Solve 20 = 4z² + z which is 0 = 4z² + z – 20 using the quadratic formula
Step-by-step explanation:
A = 2(9*11) + 1/2(8*11) + 1/2(8 * 9)
A = 198 + 44 + 36
A = 278
Answer
B. 278 in^2

About 115 are pansies when you round down from the original number (115.44)
I am pretty sure that the 117 represents the number of additional texts per month. To understand why I think so just subtract 237-120 you get 117 or 354-237 and so on which would have the same. So, the correct answer is D. The number of the additional texts per month
