1. n + 6

2. 3n

3. 3n2

4. 6n

2. 3n

Explanation:

In order to calculate the expression that represents the area of the floor you just need to remember the formula for the triangle and then you just have to insert the values given:

We know the base is 6 yd.

And the height is n yd.

So we insert the values into the formula:

Area=3n
