The formula for the perimeter of a rectangle is P=2l+2w. Which is the equivalent equation solves for w?

P-2l/2=w

P+2l/2=w

P+l=w

P-1=w

Respuesta :

P = 21 + 2w

Solve for w

Subtract 21 from both sides.


P - 21 = 2w

Divide both sides by 2.


[tex] \frac{P-21}{2} [/tex] = w

The first option is correct.
