Question 863915
The perimeter of a rectangle is 28cm. The length is 2cm less than three times the width. Determine the length and width. 
Now I have tried to solve this and I got 
3x-2=length 
And let x= width
twice the length plus twice the width=perimeter
2(3x-2)+2x=28
divide by 2:
3x-2+x=14
4x=16
x=4
3x-2=10
width=4 cm
length=10 cm
