A farmer is painting a new barn. He will need to calculate the surface area of the barn to purchase the correct amount of paint. In which of the following units can the farmer expect to calculate the surface area? m m3 ft ft2

ft^2

Step-by-step explanation:

Here in this question, we have a farmer who wants to purchase the correct amount of paint, but needs to know the surface area of the barn. We now need to select the correct unit in which the farmer would have his surface area.

In other words, what the question is simply asking us is to select which of the given units would serve as the appropriate unit for the surface area of the barn.

Mathematically, when we talk about area, we are simply talking about multiplying the length of a side with the length of another side.

We know the barn is not a single shape but shaped in terms of different segments which have different area and can be added together to give the total surface area of the barn.

Now, like we said above, we are multiplying a length by the length of another side, no matter the type of shape we are considering.

What this means is that our power( index) won’t be more than 2 since we can only multiply two sides of a particular length at a time.

So the option that would give the correct answer would be the option which has its power raised to the power of two.

The only option that fits the criterion is the last option which is the ft^2 and this in fact is the correct answer

sorry, i don't know i just need points, i'm new here. chao

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
