Estimating 75x5 would turn 75 and 5 into 70x10, which would be 700.

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

Step-by-step explanation:

Step 1: Define

Identify

Point (-1, -3.75)

Point (-1, 4.5)

Step 2: Find distance d

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

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(-1--1)^2+(4.5--3.75)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{(0)^2+(8.25)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{0+68.0625}$
[√Radical] Add: $\displaystyle d = \sqrt{68.0625}$
[√Radical] Evaluate: $\displaystyle d = 8.25$
