the length of a rectangle is 3times the width. the perimeter is 44cm. what is arethe dimensions of the rectangle?

Question

 help ini algebra 1

Answer 1

L: Rectangle length

W: Rectangle width

 

L=3W

2L+2W=44

 

2(3W)+2W=44

6W+2W=44

8W=44

W=5.5

L=16.5

 

The rectangle width is 5.5 cm.  

 

The rectangle length is 16.5 cm. 

Answer 2

Perimeter of rectangle = 2l + 2w

Given that l = 3w

 

2(3w) + 2w = 44

6w + 2w = 44

8w = 44

w = 5.5 cm

 

l = 3(5.5)

l = 16.5 cm

 

Hope this helps!

 

Answer 3

Hi Keyla,

 

let W = width

 

then length = 3w

 

P = 2L + 2W

 

44 = 2(3W) + 2W

 

44 = 8W

 

W = 5.5 cm

 

L = 16.5 cm

 

Hope this helps
