Martin wants to build an additional closet in a corner of his bedroom. Because the closet will be in a corner, only two new wall
Gekata [30.6K]

The relationship between the length & the width of the closet and the length of the wall is an illustration of a linear equation.

  • <em>The equation for f(l) is: </em>f(l) = 1.5l<em>.</em>
  • <em>The desired length and width are 8m and 4m</em>

<em />

Given that:

l = 2w

Divide both sides by 2

w = 0.5l

<u>Equation of f(l)</u>

The sum of the length and the width is represented as: f(l).

So, we have:

f(l) = l + w

Substitute w = 0.5l

f(l) = l + 0.5l

f(l) = 1.5l

See attachment for the graph of f(l)

<u>The desired dimension</u>

From the question, we understand that the total length is 12m.

This means that:

f(l) = 12

So, we have:

1.5l = 12

Divide both sides by 1.5

l = 8

Recall that:

w = 0.5l

w = 0.5 \times 8

w = 4

Hence, the desired length and width are 8m and 4m, respectively.
