Question

A rectangle has a height of 5 and a width of x2 + 2.

Answer 1

Answer:

$5 {x}^{2} + 10$

Step-by-step explanation:

The area of a rectangle is

$length \times width$

The width of the rectangle is given in terms of x as

$w = {x}^{2} + 2$

The length of the rectangle is given as:

$l = 5$

To find the area of the rectangle we multiply the two expressions to get:

$5 \times ( {x}^{2} + 2)$

We expand to get:

$5 {x}^{2} + 10$
