Answer:

7 feet

Step-by-step explanation:

The perimeter (P) of a rectangle is given by the formula:

[tex]\[ P = 2 \times (\text{Length} + \text{Width}) \][/tex]

In this case, the height is equivalent to the width of the rectangle[tex](\(\text{Width} = 14\) feet)[/tex]. You are given that the perimeter is 42 feet.

[tex]\[ 42 = 2 \times (\text{Length} + 14) \][/tex]

Now, solve for the length [tex](\(\text{Length}\))[/tex]:

[tex]\[ \text{Length} + 14 = \frac{42}{2} \][/tex]

[tex]\[ \text{Length} + 14 = 21 \][/tex]

[tex]\[ \text{Length} = 21 - 14 \]\\[/tex]

[tex]\[ \text{Length} = 7 \]\\[/tex]

So, the length of the base of the rectangle is 7 feet.
