Answer:
She needs 11374 cm to buy
Step-by-step explanation:
* Lets explain how to solve the problem
- The dimensions of the first rectangle is 1809 cm and 2891 cm
- The dimensions of the first rectangle is 738 cm and 249 cm
- Elly wants to put a fence around both
- To find the length of the fence calculate the perimeters of the two
rectangles
- The perimeter of the rectangle = 2(b + h), where b , h are the
dimensions of the rectangle
# First rectangle
∵ The dimensions are 1809 cm and 2891 cm
∵ P = 2(b + h)
∴ P = 2(1809 + 2891) = 2(4700) = 9400 cm
# Second rectangle
∵ The dimensions are 738 cm and 249 cm
∵ P = 2(b + h)
∴ P = 2(738 + 249) = 2(987) = 1974 cm
∵ The length of the fence = the sum of the perimeters of the two
rectangles
∴ The length of the fence = 9400 + 1974 = 11374 cm
* She needs 11374 cm to buy
Answer:
She needs to purchase 11374
The difference i the length of her and her brother's fence is 8442
Step-by-step explanation:
First you need to find the perimeter by adding the lengths and widths all together.
1809+2891+738+249=5687
But you need to times it by 2 because it says Elly has 2 gardens.
5687 x 2=11374.
If you are confused on the second question the answer is down below ( The person who ask this question did have to ask the second question but on my math test this question has 2 parts).
The question is Elly's brother also wants to put up a fence around his garden that is 1034 centimeters by 432 centimeters. What is the difference in the length of fence that each will purchase?
First you have to find the perimeter of Elly's brother garden.
1034+432+1034+432=2932
Last we have to find out what is the difference in the length of fence that each will purchase.
To do that you will have to subtract Elly's perimeter and Elly's brothers perimeter.
11374-2932=8442
So Elly difference in the length of the fence is 8,442.
