Question

what is the missing length?
area = 66 km²
z =
kilometers
6 km
submit

Explanation:

Step1: Recall rectangle area formula

The area of a rectangle is $A = l \times w$, where $A$ is area, $l$ is length, $w$ is width.

Step2: Rearrange to solve for $z$

Rearrange formula to $z = \frac{A}{w}$

Step3: Substitute given values

Substitute $A=66$ km², $w=6$ km:
$z = \frac{66}{6}$

Step4: Calculate the value

$z = 11$

Answer:

11 kilometers
