Question 403483
Sorry wrong question.

I will try to do it myself , and post the answer , it takes me a while because I study Algebra in Arabic so it's bit confusing when reading English.

I'll try my best !

Here is the asnwer : 

l > is the length & w > is the width 

Because a perimater of a rectangle is > 2( Width + Length ) 

& w = ( w+1 ) & l = ( 3w+2 ) 

then the equation will be  62 = 2 ( (w+1) + (3w+2) )

62 = 2w+2+6w+4
62 = 8w+6
8w = 62-6 >> w = 56/8 = 7 

Then to get the length : 

62 = 2(7+L)
62 = 14+2L
2L = 62-14 >> L = 48/2 = 24

To check your answer : 

2(7+24) = 62 ( answer is correct)
Hope I helped.
