The border will have to be 33b - 8
Step-by-step explanation:
Antoine is making a banner in the shape of a triangle
- He wants to add a decorative border around the edges
- The length of the three sides of the triangle are 9b + 8, 12b - 8 and 12b - 8
We need to find the length of the border
The length of the border is the sum of the lengths of the three sides of the triangle
∵ The length of one side = 9b + 8
∵ The length of another side = 12b - 8
∵ The length of the final side = 12b - 8
- Add the lengths of the 3 sides to find the length of the border
∴ The length of the border = 9b + 8 + 12b - 8 + 12b - 8
- Add like terms
∴ The length of the border = (9b + 12b + 12b) + (8 - 8 - 8)
∴ The length of the border = 33b - 8
The border will have to be 33b - 8
