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
