<h3>Answer:   9 square units</h3>

Explanation:

The diagram is shown below.

Side AC is the base which is 6 units long (since 9-3 = 6)

Side AB is the height which is 3 units

area = base*height/2 = 6*3/2 = 18/2 = 9

PLLLZ HELP Find Sn if a1 = 20, d = –10, and n = 25.
Ivanshal [37]

Option A: -2500 is the value of S_{25

Explanation:

It is given that the first term is a_1=20

The common difference is d=-10

We need to determine the sum of 25 terms.

The sum of  terms of an arithmetic series can be determined using the formula, S_n=\frac{n[2a_1+(n-1)d]}{2}

Substituting n=25 , a_1=20 and d=-10

Thus, we have,

S_{25}=\frac{25[2(20)+(25-1)(-10)]}{2}

Simplifying the values, we get,

S_{25}=\frac{25[40+(24)(-10)]}{2}

S_{25}=\frac{25[40-240]}{2}

Subtracting the terms within the bracket, we get,

S_{25}=\frac{25[-200]}{2}

Multiplying the terms in the numerator, we have,

S_{25}=\frac{-5000}{2}

Dividing, we get,

S_{25}=-2500

Thus, the sum of the 25 terms is -2500

Therefore, Option A is the correct answer.
