Question

Solve: A = LW/2 for L

Answer 1

A:
`L=(2A)/(W)`

Explanation:

`A=(LW)/(2)`

`(LW)/(2)=A`

`\mathrm{Multiply\:both\:sides\:by\:}2`

`(2LW)/(2)=2A`

`LW=2A`

`\mathrm{Divide\:both\:sides\:by\:}W;\quad \:W\\e \:0`

`(LW)/(W)=(2A)/(W);\quad \:W\\e \:0`

`Simplify`

`L=(2A)/(W);\quad \:W\\e \:0`

Answer 2

I think L = W/2A
