The formula for perimeter of a rectangle is given by p = 2l + 2w, where p = perimeter, l = length, and w = width. solve the formula for w.

Answer 1

The formula for perimeter of a rectangle is given by p = 2l + 2w, where p = perimeter, l = length, and w = width. solve the formula for w.

Solving for W.

P = 2L + 2W

P - 2L = 2L - 2L + 2W Subtracting 2L from both sides of the equation.

P - 2L = 2W

(P - 2L)/2 = (2W)/2 Dividing both sides of the equation by 2 to isolate the variable W.

(P - 2L)/2 = W

W = (P - 2L)/2

ANSWER: W = (P - 2L)/2

CHECKING:

Pick a rectangle with Length = 10 feet, and Width = 5 feet.

P = 2L + 2W = 20 + 10 = 30 feet

Plugging into W = (P - 2L)/2,

5 = (30 - 20)/2

5 = 10/2

5 = 5
