the width, labeled x in the figure, is 50 feet.
(type an integer or decimal.)
the length, labeled 200 - 2x in the figure, is □ feet.
(type an integer or decimal.)

Explanation:

Step1: Substitute the value of \(x\)

Given \(x = 50\), and the length formula \(l=200 - 2x\)

Step2: Calculate the length

Substitute \(x = 50\) into \(l = 200-2x\)
