Step-by-step explanation:

Area of a Rectangle

The area of a rectangle of height H and width W is:

A=H.W

The rectangle has a height of H=5 and a width of $W=4x^2-2x-6$. Calculate the area:

$A=5*(4x^2-2x-6)$

Expand the product:

$A=20x^2-10x-30$

The area of the entire rectangle is $20x^2-10x-30$
