Answer:
length 4.96 cm(4 24/25) Width 1.80 cm( 1 8/10 cm)
Explanation:
If the perimeter is 15 1/3 cm and the length is 3 1/6 cm longer than the width. Then first you have to take away 6 1/8. How did I get that? Because since a rectangle has 2 sides of length and 2 sides of width, I added 3 1/6+3 1/6. When we subtract the whole number you get 7. And when you subtract the fractions you get 5/24. I got that by doing 1/3x8 and 1/8x3. So i get a deminitor of 24. Then you have to divide 7 5/24 into 4 parts, since there is four sides. Which then you get ~1.80. That means the width is abut 1.80. And if you add the 3 1/6 back on the length it will be about 4.96.
