Answer:
The perimeter of the first question is 62
If you draw it, you'll you'll see that it's a rectangle. The length of each side is calculated by adding the widths and heights as in the photo ( red ), and then adding them up. 13 + 18 + 13 + 18 = 62
You do the same with question 2, but this time the rectangle is smaller. (green in the photo)
So the perimeter is:
13 + 14 + 13 + 14 = 54
The answer to question 3 is (-15, -5) as drawn in the photo.

<h2>Given that</h2>A finite geometric series with n = 4, a₁ = -144, and r = ½.
<h3>We have to determine</h3>What is the sum of the infinite geometric series?
<h3>According to the question</h3>The sum of the infinite is determined by the following formula;
A finite geometric series with n = 4, a₁ = -144, and r = ½.
Substitute all the values in the formula;
Therefore,
The sum of the infinite geometric series is,
Hence, the sum of the infinite geometric series is -288.
