Question

the area of a dog kennel is 28 square feet. if the length of the kennel is 4 feet, what is the width of the kennel?
a = 28 = 4×w

Explanation:

Step1: Recall the area formula for a rectangle

The area \( A \) of a rectangle is given by \( A = l \times w \), where \( l \) is the length and \( w \) is the width. We know \( A = 28 \) square feet and \( l = 4 \) feet. We need to solve for \( w \).

Step2: Rearrange the formula to solve for width

From \( A = l \times w \), we can solve for \( w \) by dividing both sides by \( l \). So, \( w=\frac{A}{l} \).

Step3: Substitute the known values

Substitute \( A = 28 \) and \( l = 4 \) into the formula: \( w=\frac{28}{4} \).

Step4: Calculate the result

\( \frac{28}{4}=7 \).

Answer:

The width of the kennel is 7 feet.
