Explanation:

Step1: Recall area formula

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

Step2: Rearrange formula for length

We can rewrite the formula as $l=\frac{A}{w}$.

Step3: Substitute values

Given $A = 136$ square - centimeters and $w = 8$ centimeters. Then $l=\frac{136}{8}=17$ centimeters.

Answer:

C. 17 cm
