To solve A =lw for l it means you want l on one side of the equals and anything not l on the other side. How are l and w put together? They are multiplied. We undo that multiplying with dividing.

A = l * w

A / w = l to divide both sides by w.

Thus l = A / w.

Answer:

The required formula is [tex]l=\frac{A}{w}[/tex].

Step-by-step explanation:

The given formula is

[tex]A=lw[/tex]

Where, A is the area of a rectangle, l is length of the rectangle and w is the width of the rectangle.

To find the formula for l, we have to isolate the variable l.

Divide both sides by w.

[tex]\frac{A}{w}=\frac{lw}{w}[/tex]

[tex]\frac{A}{w}=l[/tex]

Therefore the required formula is [tex]l=\frac{A}{w}[/tex].
