Question

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?​

Answer 1

y²+4y

Explanation:

y multiplies with (y+4)

y times y is y²

y times 4 is 4y

That leaves you with y²+4y

Answer 2

Answer:
`y^2+4y` expresses the area.

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

`Length* breadth\\\\=y* (y+4)\\\\=y^2+4y`

Hence,
`y^2+4y` expresses the area.
