1. The perimeter = 3.7 + 3.7 + 2.8 + 2.8
= 13
The area = 3.7 * 2.8 = 10.36

2. Perimeter = 11.2
Area = half base times height
2.6 * 1.5 = 3.9 squared

Distance Formula: $\displaystyle d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Step-by-step explanation:

Step 1: Define

Identify.

Point (-7, 1)

Point (-7, -5)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d.

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(-7 - -7)^2 + (-5 - 1)^2}$
[Order of Operations] Evaluate: $\displaystyle d = 6$
