Question

the perimeter of a rectangle is 60 meters. if the length of the rectangle is 14 meters. what is the width of the rectangle.,

Answer 1

Perimeter is 2width+2length
Therefore since you already know that the perimeter is 60 and the length is 14 you can set up the equation; 
60= 2w+14
with this you then need to find w so;
60=2w+14
-14     -14
46=2w
(46/2)=(2w/2)
13=w
The width is 13

Answer 2

Perimeter= length+length+width+width

if one side is 14 the other side is too :
14 + 14 = 28

now subtract :
60-28=32

then divide to find the width :
32÷2=16

the width of the rectangle is 16 meters



hope this helped
