Ted needs new edging around most of his flower bed. The edging on the narrow end does not need to be replaced. Write and evaluate a numerical expression to find how many feet of edging Ted needs.

To find how many feet of edging Ted needs, we can add up the lengths of the three sides of the flower bed that need to be replaced.
Let's say the length of the narrow end that does not need to be replaced is 'a' feet.
Let's say the width of the flower bed is 'b' feet.
Let's say the length of the long side that needs to be replaced is 'c' feet.
The total length of the edging needed is then:
a + b + c feet
Since the edging on the narrow end does not need to be replaced, we can simplify the expression to:
b + c feet
We need the values of 'b' and 'c' to evaluate the expression and determine the exact number of feet of edging Ted needs.
To find the total number of feet of edging Ted needs, we need to add up the lengths of the sides of the flower bed that require new edging.
Let's say the length of the flower bed is L feet, and the width of the flower bed is W feet. The narrow end of the flower bed does not need to be replaced, so we subtract the width from the total length of the flower bed.
Therefore, the length of the sides that require new edging can be calculated as:
Length of one long side = L - W
Length of the other long side = L - W
To find how many feet of edging Ted needs, we sum up these lengths:
Total length of edging = (L - W) + (L - W)
Now, let's evaluate a numerical expression using specific values for the length and width of the flower bed. Assuming the length is 10 feet and the width is 3 feet, we can substitute these values into the expression:
Total length of edging = (10 - 3) + (10 - 3)
= 7 + 7
= 14 feet
Therefore, Ted needs a total of 14 feet of edging for his flower bed.
