S=2(lw+lh+wh) solve for w

wolverine [178]

we have

$s=2(lw+lh+wh)$

Solve for w means that clear variable w

$s=2(lw+lh+wh)\\s=2lw+2lh+2wh$

Group terms that contain the variable w, and move the other terms to the opposite side of the equation

$(s-2lh)=(2lw+2wh)$

Factor the variable w

$(s-2lh)=w(2l+2h)$

Divide both sides by $(2l+2h)$

$(s-2lh)/(2l+2h)=w(2l+2h)/(2l+2h)$

$w=(s-2lh)/(2l+2h)$

therefore

<u>the answer is</u>

$w=(s-2lh)/(2l+2h)$
