Perimeter and area help?

Question

the formula for the perimeter of rectangle is given P=2l+2w, where l is the length and w is the width

solve for w?

please help!

thanks in advance:)

Answer 1

w = P/2 - l

Answer 2

P = 2l + 2w (subtract 2l from both sides)

P - 2l = 2w (divide both sides by 2)

(P - 2l)/2 = w

w = (P - 2l)/2

w = P/2 - l <===ANSWER

Answer 3

P=2l+2w

P-2l=2w

Divide everything by 2.

(P/2)-l=w

Answer:(P/2)-l=w or P divided by two minus l equals w.

They want you to solve for w so if you had values for l and p, you could just do the equation you just created.
