Lesson 25-- Math in Our World: Field Trip to the Zoo
Introduction
Hello Mathematicians! Today we will once again use area and perimeter to solve real- world problems.
Take a look at these images. Which of these does not belong? (P= Perimeter and A= Area) Jot down your thoughts in your math notebook.

Part 1 Directions:
- Your class is taking a field trip to the zoo.
- While at the zoo, your team will participate in a scavenger hunt! Your goal is to stop by different habitats where the animals live. Your team will either determine the distance around the animals’ living space, or how much material (mulch, grass, woodchips) it takes to cover their
zoo habitat. Use the diagram and clues below to help you. (**Model is not to scale.)
- 1. The zookeeper needs to take fresh food and water to the animals that live in a cage that has an area of 100 square yards. Where should he take it?
- 2. Take a visit to the animals that live in a habitat that has a perimeter of 30 yards around with an area of 36 square yards. Where will you go?
- 3. Certain animals like to graze in an area that’s covered with 70 square yards of grass in a habitat that has a perimeter of 38 yards. What animal lives in this habitat?
- 4. A certain animal pen is 20 feet in perimeter. Which animal lives in this habitat? What is the area of this habitat?
- 5. The zookeeper has enough fresh sod to cover a pen that has an area of 180 square feet. Where should the sod go?

Part 2 Directions:
- You have been hired to design the new Zoo of Georgia!
- Architects need your help to design a zoo that houses animal exhibits representing the five regions of Georgia. You will use your knowledge of area and perimeter to design each
space (animal enclosures, walking paths, buildings, restrooms, etc.) - Architects have asked you to include the following in your design:
- You need at least 6 different animal exhibits to represent animals native to Georgia. Exhibits should be square or rectangular.
- Walking paths should be included between animal exhibits and buildings.
- Include at least one entrance.
- The property must have at least two restrooms.
- A food pavilion must be included.
- You will need to include a souvenir shop.
- A customer service building is a must.
- Create a colorful display of your design using grid paper. Record the area and perimeter of
each space in your zoo.
| Location | Dimensions | Area | Perimeter |
|---|---|---|---|
| Elephant Exhibit | 20 yds X 9 yds | 180 square yards | 58 yds |

Challenge:
Choose one of your enclosures and redraw it with a missing measurement using a symbol for the unknown. Challenge someone to figure out the missing measurement using their knowledge of area and perimeter.
Example: The rectangular reptile enclosure has a perimeter of 260 feet. The width is 60 feet. What is the length? What is the area?
