Anyone knows how to do this

length = x - 2

Step-by-step explanation:

The area (A) of a rectangle is calculated as

A = length × width

Here A = x² - 7x + 10 and width = x - 5

x² - 7x + 10 = length × (x - 5) ← divide both sides by (x - 5)

length = ← factor the numerator

           = ← cancel common factor (x - 5) on numerator/ denominator

           = x - 2

Thus length = x - 2 metres

for the points! : )
