Question

If the area of a rectangular garden is 45x2−12x square meters, and it has a length of 3x meters, what is its width?

Answer 1

15x-4

Explanation:

Like the previous answer, AREA= length*width

We are given the area, which is 45x^2 - 12x. We are also given the length which is 3x. Using long division, we see (45x^2 - 12x)/3x.

The answer, which is the width, is 15x-4.

Answer 2

(9x -4) meters

Explanation:

The relationship between area, length, and width is ...

area = length × width

Dividing by length gives ...

width = area/length

Filling in the given expressions, we have ...

`w=(45x^2-12x)/(3x)=(45x^2)/(3x)-(12x)/(3x)=9x-4`

The width of the garden is 9x-4 meters.
