Answer:

17x - 11y + 14 cm

Explanation:

In order to find the perimeter of a triangle, we simply add up the lengths of all three sides.

Perimeter = side 1 + side 2 + side 3

In this case:

Given:

  • Side 1 = 8x + 4 cm
  • Side 2 = 9x - 4y cm
  • Side 3 = 10 - 7y cm

Solution:

Perimeter = 8x + 4 + 9x - 4y + 10 - 7y

Simplify like terms:

= 17x - 11y + 14

Therefore, the perimeter of the triangle is 17x - 11y + 14 cm.
