Answer:
The perimeter of the entire plot of land is 88 feet
Explanation:
* Lets explain how to solve the problem
- A plot of land contains a garden
- The dimension of the garden are 16 feet by 20 feet
- The garden is surrounded by a 2 feet wide wall on all sides
- That means its dimension of the garden will increase by 2 feet
from each side
- Let the width of the garden is 16 feet and its length is 20 feet
∵ The width of the garden is 16 feet
∵ It is increased from each side by 2 feet
∴ The width of plot land = 16 + 2 + 2 = 20 feet
∵ The length of the garden is 20 feet
∵ It is increased from each side by 2 feet
∴ The length of plot land = 20 + 2 + 2 = 24 feet
∴ The dimensions of the entire plot of land are 20 feet by 24 feet
∵ The perimeter of the land = 2(the sum of its dimensions)
∵ The dimensions are 20 feet and 24 feet
∴ The perimeter of it = 2(20 + 24) = 2(44) = 88 feet
∴ The perimeter of the entire plot of land is 88 feet
