Find value of unknown variable ?

Question

P=2l+2w

 

If l=3.75 and P= 12.26

Answer 1

Hi Alex,

 

It looks like you are trying to solve for w.

 

P = 2l+2w

 

Entering the values for the variables we know.

 

12.26 = 2(3.75) + 2w

12.26 = 7.50 + 2w

 

Subtract 7.50 from both sides

4.76 = 2w

 

Divide both sides by 2

2.38 = w
