Hi there!
The question is asking us to find the rectangle's area.
To find the area, we use the formula:

Here,
◈ A = area
◈ l = length
◈ w = width
In this problem,
◈ A is unknown
◈ l = (x + 5) units
◈ w = (5x - 11) units
◈◈◈◈◈◈◈◈◈◈◈◈◈◈◈◈◈◈◈
Plug in the data :-

To simplify, use FOIL :-
◈ First
◈ Outside
◈ Inside
◈ Last
Multiply the first terms : 5x * x = 5x²
Multiply the outside terms : x * (-11) = -11x
Multiply the inside terms : 5 * 5x = 25x
Multiply the last terms: 5 * (-11) = -55
Combine the terms: 5x² - 11x + 25x - 55
5x² + 14x - 55
Therefore, the rectangle's area is 5x² + 14x - 55 square units.
Have a fantastic day!
