THE LENGTH OF A RECTANGLE IS 6 TIMES THE WIDTH. THE PERIMETER OF THE RECTANGLE IS 105. WHAT IS THE LENGTH AND WIDTH OF THE RECTANGLE?

Question

anonymous · Answer

don.t understand

anonymous · Answer

L = 6w

so P = the sum of the sides , then we have :

P = 6w + 6w + w + w
105 = 14w
so w = 15/2 
and L = 2(w)
         = 2(15/2)
         = 15

^_^ I guess

L=6W= 6(15/2)=45

alina, this answer is fine, except sstarica just made a slight error at the end which AnwarA corrected for.

sstarica had everything right up to the line, w=15/2.  After that, where he/she has written L=2(w), that's wrong, but it's a typo since he/she had the relationship between L and w right at the beginning.

The width calculated by sstarica is correct.  Then take the width and use L=6w like AnwarA did.  

Is that okay?
