Your answer would be 64 in².
To find the surface area, you just need to find the area of each of the shapes shown and add them together.
We can find the area of one of the triangles by doing:
(base × height)/2
(6 × 4)/2 = 24/2 = 12
As there are 4 identical triangles, the area of all of them would be 12 × 4 = 48 in².
Now we need to find the area of the square in the middle, which would be 4 × 4 = 16 in².
Adding these together gives us 16 + 48 = 64 in²
I hope this helps!
Since we have 2 numbers, we'll be square rooting.
All we have to do to find the mean is multiply & square root the products.
30 × 6 = 180

You can use the same process and check my answer if you'd like; I rounded the square root, so you may get a different answer.
What are the demetions of the platform?
Answer:
For every 4 cats there are 5 dogs, the total number of animals is 24. If we were to do the math we would see that all you need to do is add the amounts to equal the total.
Step-by-step explanation:
When you go to add/ adjust the amount or ratio make sure it is the same equation for both cats as it is dogs
Cy + b ÷a
Hope this helps :)
