Answer:

y = 3

Perimeter: 17 ft

Step-by-step explanation:

3y - 2 = y + 4

2y = 6

y = 3

Perimeter: 4 + 6 + (3 + 4)

10 + 7

17

Both triangles are the same dimensions set the two equations equal and solve for y:

3y -2 = y +4

Add 2 to both sides:

3y = y + 6

Subtract 1y from both sides:

2y = 6

Divide both sides by 2:

Y = 3

Perimeter = ((3(3)-2 =9-2= 7):

7 + 4 + 6 = 17 feet
