Answer:
Area :81 Perimeter: 12
Step-by-step explanation:
First you need to find the length, which would be 27, because it says the length is 3 times the width, so the length is 27, and then for perimeter you just add the sides you have data for, so 9+3, which is 12. Then the area would be length times width, so 9 times 27, which is 243.
