Step-by-step explanation:

theres 4 different subjects that could be in each of 4 different slots, eg, science, ss, ela, or math could be in slot one, or the same for slot two, and so on and so forth.4 x 4 = 16

Step-by-step explanation:

If 5 cm on the model = 4 feet in real

Then, what does 1 cm on the model = in real?

5/4=1.25

So, 1 cm on the model = 1.25 ft

Now, what does 3cm long in the model = to in real?

1.25x3=3.75

So hence, the length of the Dog house is actually 3.75 feet.
