Answer:
13 cm and 3 cm
Step-by-step explanation:
The area of the rectangle is 39 cm^2, so the length and width must multiply to equal 39. Since the length, or L, is 4 cm more than 3 times the width, or W, which makes an equation like this, L=3W+4
In this case, 13 is 4 more than 3 times of 3, or 9, since 9+4=13. So, the length of the rectangle is 13 cm while the width is 3 cm.
Hope this helps!
