For problem #1 There is a formula to find the measure of each interior angle in aNy polygon. This formula is (n-2)*180 divided by n

n stands for the number of sides of a polygon

In this case we have a NONAGON so the value of n would be 9

Plug that value of n into the formula and you should get your answer in degree units ;)


For #2, the first shape is a trapezoid. There is a formula for the area of a trapezoid and this is Area=  \frac{a+b}{2}*h

a= the base of the trapezoid (let's say that is 9 units)

b= the other base of the trapezoid (this would be 15 units)

h= the height of the trapezoid (8 units)

Plug the numbers into the formula I gave you and you should get your answer in units squared


b) The second shape is a regular hexagon.  We know it's regular because they show you the tick marks that means that all the sides in that hexagon are the same length.

The formula is Area = \frac{1}{2}*a*p

a= the apothem which is the length going from the center straight down to the edge forming a 90-degree angle. They give you this length in the drawing which is 3 units. 

p= perimeter The perimeter can be found by adding up all the sides of the hexagon. They tell you each side is 4 units and the hexagon has 6 sides, so the perimeter is 4+4+4+4+4+4= 24 units

Plug the numbers into the formula I gave you and you should get your answer in units squared


c) To find the area of the next shape, you can split the figure into three different shapes composed by a parallelogram, a trapezoid, and a rectangle.
I already gave you the formula to find the Area of the trapezoid so I hope you can figure that out. If you struggle, reach out and I can help.The area of a parallelogram is A=base*height and the area of a rectangle is A=side*side
Add up those 3 areas and you will get your answer!

A triangle has an area of 900m2 . If a parallelogram has the same height and base as the triangle, what is the area of the paral
timama [110]

Answer:

1800 m^{2} is the area of parallelogram.

Step-by-step explanation:

Given that:

Area of a triangle = 900 m^{2}

To find:

Area of a parallelogram which has same height and base as that of the given triangle.

Solution:

First of all, let us have a look at the formula for Area of a parallelogram:

Area_{Par} = Base \times Height ...... (1)

So as to find the area of a parallelogram, we need to have the product of Base and Height of Parallelogram.

Now, let us have a look at the formula for area of a triangle:

Area_{Tri} = \dfrac{1}{2} \times Base \times Height

Given that height and base of triangle and parallelogram are equal to each other.

So,the product of base and height will also be equal to each other.

900 = \dfrac{1}{2} \times Base \times Height\\\Rightarrow Base \times Height = 2 \times 900\\\Rightarrow Base \times Height = 1800\ m^2

By equation (1):

<em>Area of parallelogram = 1800 </em>m^{2}<em> </em>
