Please answer correctly !!!!!!!! Will mark brainliest !!!!!!!!!!

Answer:
(x-5)
Step-by-step explanation:
x^2 -25
We know this is the difference of square
(x-5)(x+5)
Since the length is (x+5) the width must be (x-5)
Given:
To be calculated:
Calculate the width of rectangle?
Formula used:
Area of Rectangle = L × b
Solution:
We know,
Area of Rectangle = L × b
⇒ x² - 25 = x + 5 × b
⇒ b = x² - 25 / x + 5
⇒ b = x² - 5² / x + 5
⇒ b = ( x + 5 ) ( x - 5 ) / x + 5
⇒ b = x - 5
