The formula for the perimeter of a rectangle is P=2(l+w).

Solve for w.

Step-by-step explanation:

Consider the provided equation.

P=2(l+w)P=2(l+w)

We need to solve the equation for I.

Divide both the sides by 2.

{P}{2}=\frac{2(l+w)}{2}2P=22(l+w)

{P}{2}=l+w2P=l+w

Now isolate the variable I.

Subtract w from both side.

\{P}{2}-w=l+w-w2P−w=l+w−w

I{P}{2}-wI=2P−w

The value of the equation for I is I=\frac{P}{2}-wI=2P−w .

Idk but this might help o_o

answer: 180

step-by-step explanation:

12-2=10

20-2=18

10x18=180
