Question

What is the perimeter of the object (Hint: some numbers are missing)

Answer 1

Answer: It is 70.

Step-by-step explanation: Once you add them all up. 15+12+7=8+5+23=70.

The length of the small missing side is 5. 12-7=5. The length of the big missing side is 23, because 15+8=23. So the answer is 70

Answer 2

15 + 12 + 7 + 8 = 42

8 + 15 = 23

12 - 7 = 5

23 + 5 = 28

42 + 28 = 70 mm
