The area of the following shape is 50
D) initial value of 60 and multiplying by 1/3
It is not a multiple of 8
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.
