A rectangle has 4 sides. Two of the sides have the same length, and the other two sides have the same length. Therefore, two sides are x+4 and the other two are equal to x.
Your equation will be (x+4)+(x+4)+x+x=48
When you solve for x, you get 10.
Since your length is x+4, you will do 4+10 which is 14 as your final answer
FINAL ANSWER: 14''
