You have a rectangle with the followinf expressions for its sides:

w: width = 5x² + 2x - 3

h: height = x + 4

In order to calculate the area of the rectangle, you use the following formula for the area:

A = w*h

By replacing w and h by the given algebraic expressions you have:

A = (5x² + 2x - 3)(x + 4) use distribution property

A = 5x²(x) + 5x²(4) + 2x(x) + 2x(4) - 3(x) - 3(4) simplify

A = 5x³ + 20x² + 2x² + 8x - 3x - 12 simplify similar terms

A = 5x³ + 22x² + 5x - 12

Hence, the total area of the figure is 5x³ + 22x² + 5x - 12

The parking space shown at the right has an area of 209 ft2. A custom
jeyben [28]

Given:

The parking space shown at the right has an area of 209 ft².

A custom truck has rectangular dimensions of 13.5 ft by 8.5 ft.

To find:

Whether the truck fit in the parking space or not?

Solution:

If the area of the truck is more than the area of the parking space, then the truck cannot fit in the parking space otherwise it will fit in the parking space.

The area of a rectangle is:

Area=length\times width

Area of the rectangular truck is:

Area=13.5\times 8.5

Area=114.75

The area of the truck is 114.75  ft² which is less than the area of the parking space, 209 ft².

Therefore, the truck can fit in the parking space because the area of the truck is less than the area of the parking space.
