A homeowner is planning to fence in a play area for his dog Moose, and he decides that he’d like to spend no more than the cost of 160 feet of fence. But since he wants Moose to have plenty of room for chasing squirrels, he decides to use the full 160 feet. He also wants the play area to be rectangular. Use the smooth marked scatter plot to create a graph describing the width and area and answer the following questions.
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

Use the smooth marked
1.) If you decide to make the play area 5 feet wide, how long would it be?
2.) What would the length be if the play area is 50 feet wide?
3.) Based on the graph, what width makes the area as large as possible?
4.) What’s the area of the largest possible pen he can make out of 160 feet of fence?
| Width (ft) | Area (sq ft) |
| 5 | 375 |
| 10 | 700 |
| 20 | 1200 |
| 30 | 1500 |
| 40 | 1600 |
| 50 | 1500 |
| 60 | 1200 |
| 70 | 700 |
| 80 | 0 |
