The width of a rectangle is y feet long. The rectangle is 4 feet longer than it is wide. What is the area of the rectangle? Which expression represents the area?​

Respuesta :

Answer:

y²+4y

Step-by-step explanation:

y multiplies with (y+4)

y times y is y²

y times 4 is 4y

That leaves you with y²+4y

Answer: [tex]y^2+4y[/tex] expresses the area.

Step-by-step explanation:

Let the width of a rectangle be 'y' feet.

Let the length of a rectangle be 'y+4' feet.

As we know the area of rectangle :

Area of rectangle is given by

[tex]Length\times breadth\\\\=y\times (y+4)\\\\=y^2+4y[/tex]

Hence, [tex]y^2+4y[/tex] expresses the area.
