Answer:

Area = 8x² - 14x + 5

Perimeter = 12x - 12

Step-by-step explanation:

The area of the rectangle can be calculated as the base times the height, so the area is equal to:

Area = Base · Height

Area = (4x - 5)·(2x - 1)

So, applying the distributive property, we get:

Area = 4x(2x) + 4x(-1) - 5(2x) - 5(-1)

Area = 8x² - 4x - 10x + 5

Area = 8x² - 14x + 5

On the other hand, the perimeter is equal to:

Perimeter = 2(Base) + 2(Height)

Perimeter = 2(4x - 5) +2(2x - 1)

Perimeter = 2(4x) - 2(5) + 2(2x) - 2(1)

Perimeter = 8x - 10 + 4x - 2

Perimeter = 12x - 12

Then, the answers are:

Area = 8x² - 14x + 5

Perimeter = 12x - 12
