Answer:

135 cm²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = \frac{1}{2} h(a + b)

where h is the height and a, b the parallel bases

Here h = 9, a = 13 and b = 17 , thus

A = \frac{1}{2} × 9 × (13 + 17)

   = 0.5 × 9 × 30

   = 135 cm²

Can a sequence be both arithmetic and geometric at the same time
erastova [34]
Yes, it can both arithmetic and geometric.

The formula for an arithmetic sequence is: a(n)=a(1)+d(n-1)

The formula for a geometric sequence is: a(n)=a(1)*r^(n-1)

Now, when d is zero and r is one, a sequence is both geometric and arithmetic.

This is because it becomes a(n)=a(1)1 =a(1). Note that a(n) is often written an

It can easily observed that this makes the sequence a constant.
