A=l×w solve for w

Question

Please show me step by step

Answer 1

This is the formula for the area of a rectangle.

 

A=LxW....to solve for W, simply divide both sides of equation by "L"

              to isolate W.

A/L=(LxW)/L....L/L on right hand side of equation is equal to one.

A/L=W

W=A/L

 

Answer 2

When solving for a variable, the goal is to isolate that variable on one side of the equation.

 

If we divide both sides of the equation by l, we get

 

A ÷ l = w

 

 

In algebra, we use a "slash" or a "fraction bar" to represent division.

 

A / l = w
