Question

Micaela measures her floor and finds its length to be 0.6 m longer than the width w. Which function rule describes A, the area of the floor of Micaela's room?

Answer 1

The area function can be given as:

`A(w)=w^2+0.6w`

Explanation:

Given:

Width of the floor =
`w` meters

Length is 0.6 meters longer than the width

To find the function rule that describes area
`A` of the floor of Micaela's room.

Solution:

Width of floor in meters =
`w`

So, length of the floor would be given in meters as =
`(w+0.6)`

Area =
`length* width`

Thus area
`A` of the floor as a function of width can be expressed as:

`A(w)=w(w+0.6)`

Using distribution:

`A(w)=w^2+0.6w` (Answer)
