The perimeter of the triangle is 17k + 13n - 8m
The perimeter of a triangle is the sum of it's 3 sides ;
If the sides are a, b and c.
The perimeter will be :
(a + b + c)
Given the side lengths
- (9k - 4m)cm
- 9k - 4m)cm(8k + 3n) cm
- 9k - 4m)cm(8k + 3n) cm (9n - 4m) cm
The perimeter of the triangle will be :
9k - 4m + 8k + 3n + 9n - 4m
Collect like terms :
9k + 8k +3n + 9n - 4m - 4m
17k + 13n - 8m
Hence, the perimeter of the triangle is 17k + 13n - 8m
