answer = 56

answer:

w = 4 1/3

l = 10 2/3

step-by-step explanation:

let w = width

l= length = w+ 6 1/3

  changing the mixed number to an improper fraction  

6   1/3 = (3*6+1)/3 = 19/3

l = w + 19/3

fencing means perimeter

p = 2(l+w)

30 =2(l+w)

replace l with w+19/3

30 = 2 (w + 19/3 +w)  

combine like terms

30 =2(2w+19/3)

divide by 2 on each side

30/2 = 2/2 (2w+19/3)

15 = 2w+19/3

subtract 19/3 from each side

15 -19/3 = 2w+19/3-19/3

45/3 -19/3 =2w

26/3 =2w

multiply by 1/2

26/3 *1/2= 2w*1/2

26/6 = w

change this back to a mixed number

6 goes into 26 4 times   (6*4=24   ) with 2 left over

4 2/6

4 1/3

w = 4 1/3

l = w + 6 1/3

l = 4 1/3 + 6 1/3

l = 10 2/3

answer:

0.24 is not 2/4.

0.24 is 24/100.
