Question

a rectangle has a height of 5 and a width of $x^{2}+2$. express the area of the entire rectangle. expression should be expanded.

Explanation:

Step1: Recall area formula

$A = h\times w$ (where $A$ is area, $h$ is height, $w$ is width)

Step2: Substitute values

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

Step3: Apply distributive property

$A = 5\times x^{2}+5\times2$

Step4: Simplify

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

Answer:

$5x^{2}+10$
