Answer:

126.4

Step-by-step explanation:

If you put three squares that are all 15.8cm together, you get a rectangle that is 47.4cm by 15.8cm. To get 47.4, you multiply 15.8 x 3 because it's three 15.8 squares together. Then to find the perimeter of the rectangle, you add all the sides together to get the answer 126.4.
