Question

Solve the formula P = 2l + 2w for w.

​

Answer 1

We are given the following equation :

`{:\implies \quad \sf P=2L+2w}`

And we need to solve for w, so let's start :

`{:\implies \quad \sf P=2L+2w}`

Now, transpose 2L to LHS ;

`{:\implies \quad \sf P-2L=2w}`

`{:\implies \quad \sf 2w=P-2L}`

`{:\implies \quad \boxed{\bf{w=((P-2L))/(2)}}}`

Hence, Option a) is correct
