Question
Find the length of each side and the perimeter. (5n -17) cm (2n + 1) cm n cm
Answer
The length of the first side is 5n - 17cm, the length of the second side is 2n + 1cm, the length of the third side is ncm, and the perimeter is 8n - 16cm.
- Find the length of the first side: 5n - 17cm.
- Find the length of the second side: 2n + 1cm.
- Find the length of the third side: ncm.
- Add the lengths of all three sides to find the perimeter: (5n - 17) + (2n + 1) + n = 8n -16cm.
