To find the length of Javier's yard, we need to use the area of the rectangular yard formula, which is:
\[ \text{Area} = \text{Length} \times \text{Width} \]
Javier has a width of 14 ft and an area of 378 ft². We can set up the equation:
\[ 378 = \text{Length} \times 14 \]
To find the length, we can solve for "Length" by dividing both sides by 14:
\[ \text{Length} = \frac{378}{14} \]
Now, let's calculate:
\[ \text{Length} = 27 \text{ ft} \]
Looking at the options provided:
A: \( 2 \text{ tens} + 2 = 22 \)
B: \( 2 \text{ tens} + 4 = 24 \)
C: \( 2 \text{ tens} + 7 = 27 \)
D: \( 2 \text{ tens} + 8 = 28 \)
The correct answer is C: \( 2 \text{ tens} + 7 = 27 \) ft.
