Question 745571
length of a rectangle is 5 inches more than double its width means:

l=2w+5

 the perimeter is 70 inches means:

2l+2w=70

or l+w=35

subbing in for l and simplifying...

(2w+5)+w=35

3w=30

so w=10

then that means 

l+10=35

and so l=25

the dimensions must be: 25 inches x 10 inches
