Question

The perimeter of the triangular park shown on the right is 11x - 7. What is the missing length?

Answer 1

6x-4

Explanation:

the perimeter is the distance around the shape, we get this by adding all the sides, call the missing side y and set up an equation for the perimeter

11x-7 = 4x+2 + x-5 + y

solve for y

11x-7 = 5x -3 + y

11x-4 = 5x + y

6x-4 = y
