Answer:
[tex]5 {x}^{2} + 10[/tex]
Step-by-step explanation:
The area of a rectangle is
[tex]length \times width[/tex]
The width of the rectangle is given in terms of x as
[tex]w = {x}^{2} + 2[/tex]
The length of the rectangle is given as:
[tex]l = 5[/tex]
To find the area of the rectangle we multiply the two expressions to get:
[tex]5 \times ( {x}^{2} + 2)[/tex]
We expand to get:
[tex]5 {x}^{2} + 10[/tex]
