Divide each number by 3
Then subtract the numbers you got from the answers that you divided

3. The area of a triangle can be given by (just plug and chug as always):

The area of the triangle is
6ft².
4. I will divide into a triangle and a rectangle (because the actual equation for the area of a pentagon requires it to be a perfect pentagon). Let's do the triangle first (height is 3 because you subtract 12 from 15):


Now we just add them:

So, the area of that pentagon is
108m².
5. You are actually wrong on this one because the area of a triangle is:

So, just halve your answer and it will be correct.
6. We can just split it into 4 triangles of equal area and then multiply the area of 1 triangle by 4 to get the total area. Let's do just that:

Multiply by 4 to get total area:

So, the area of the given rhombus is
25cm².
Answer:
748.23 in²
Step-by-step explanation:
<u>Area of a Regular Polygon</u>

where:
- n = number of sides
- l = length of one side
- a = apothem
Given:
- n = 6
- l = 101.8 ÷ 6
- a = 14.7
Substituting the given values into the formula and solving for A:




Therefore, the area of the hexagon is 748.23 in²
I believe it should be 1.0 mol
Answer:
16°C
Step-by-step explanation:
10° - (-6°) = 16°C
