Kayla wants to fence in a rectangular dog pen that is 30 ft by 40 ft How would you use wha you know about geometry to help her ensure that she has truly built a rectangular pen?

Kindly check explanation

Step-by-step explanation:

Given the dimension of the dog pen = 30 ft by 40 ft.

Using the knowledge of geometry, that know that a rectangle has been built, the area of the pen should be :

Area of rectangle = Length * width

Area = 40 * 30

Area = 1200 ft²

Perimeter of rectangle = 2(Length + width)

Perimeter = 2(40 + 30)

Perimeter = 2(70)

Perimeter = 140 feets

Hence, area of the pen should be 1200 ft² and its perimeter or fencing should measure 140 feets

a. the residual plot for model 1 has a random pattern and is a good fit for the data.

tube or goog would be a great resource to with that question
