The Perimeter of a rectangle is 168ft , with the length of 46ft. What is the width?

Question

perimeter of a rectangle is 168ft, What is the width?

Answer 1

P=2l+2w

(1/2)P=l+w

168/2=84

84=46+w

w=84-46

w=38 feet

Answer 2

So, the perimeter of a rectangle is all sides added together:

 

l + l + w + w = P (where l is the length and w is the width).

 

You can rewrite this as:

 

2l + 2w = P

 

For the problem then:

 

2(46) + 2w = 168

 

92 + 2w = 168

 

Subtract 92 from both sides:

 

2w = 76

 

Divide both sides by 2:

 

w = 38ft (the width)

Answer 3

Perimeter = 2 * length + 2*width

168 = 2(46) + 2w

168 = 92 + 2w

76 = 2w

w = 38
