I believe it would be c
This is because when you have to find a line that is perpendicular you have to flip the nominator and denominator and then change the sign so if it’s negative switch it to positive

A rectangle’s width is 2 meters shorter than its length, l. Its area is 168 square meters. Which equation can be used to find th

bija089 [108]

Answer:

l(l - 2) = 168

Step-by-step explanation:

Let w = width

Let l = length

Let A = area

w = l - 2

A = l * w

also, A = 168

equating the two values of A

l * w = 168

l * (l - 2) = 168

l^2 - 2l = 168

l(l - 2) = 168

Look at the picture.

the length of horizontal segment: |10 - 4| = |6| = 6

the length of vertical segment: |8 - 3| = |5| = 5

Use the Pythagorean thorem:

$x^2=6^2+5^2\\\\x^2=36+25\\\\x^2=61\to x=\sqrt{61}\ mi.\\\\\sqrt{61}\approx7.81\ mi.$
