Answer:

p=240cm

Step-by-step explanation:

Imagine this is the nine box where each measures 20 cm, to calculate for the side of the big square we must multiply 20 cm by 3.

20cm×3 = 60cm

Now, we have the measurement of the side of the big box.

We will use the formula p=4a to calculate for the perimeter of the big square

p=4(measure of the side)

p=4(60cm)

p=240cm
