Final answer:
To find the total length of fencing Annie needs to buy to completely surround her garden, she needs to calculate the perimeter of the garden. The perimeter is the sum of the lengths of all the sides of the garden. She can simply measure the lengths of all the sides of her garden and then add them together.
Step-by-step explanation:
To find the total length of fencing Annie needs to buy to completely surround her garden, she needs to calculate the perimeter of the garden.
The perimeter is the sum of the lengths of all the sides of the garden.
If Annie knows the measurements of each side of the garden, she can simply add them together to find the total length of fencing needed.
In this case, Annie needs to measure the lengths of all the sides of her garden and then add them together.
Let's say the lengths of the sides are A, B, and C.
She would calculate the total length of fencing needed using the equation:
Total length = A + B + C.
For example, if the lengths of the sides are 80 feet, 105 feet, and 90 feet, Annie would calculate the total length of fencing needed as follows:
Total length = 80 + 105 + 90 = 275 feet.
