<u><em>Answer:</em></u>

Area of the polygon = 59 in²

<u><em>Explanation:</em></u>

From the given diagram, we can note that the given polygon is composed of an upper triangle, a side triangle and a rectangle

<u>Therefore:</u>

Area of polygon =

area of upper triangle + area of side triangle + area of rectangle

<u>1- getting the area of the upper triangle:</u>

<u>We have:</u>

base of triangle = 7 in

height of triangle = 6 in

<u>Therefore:</u>

Area of upper triangle = \frac{1}{2}*base*height = \frac{1}{2}*7*6=21 in²

<u>2- getting the area of the side triangle:</u>

<u>We have:</u>

base of triangle = 4 in

height of triangle = 5 in

<u>Therefore:</u>

Area of upper triangle = \frac{1}{2}*base*height = \frac{1}{2}*4*5=10 in²

<u>3- getting the area of the rectangle:</u>

<u>We have:</u>

length of rectangle = 7 in

width of rectangle = 4 in

<u>Therefore:</u>

Area of rectangle = length x width = 7 x 4 = 28 in²

<u>4- getting the total area of the polygon:</u>

Area of polygon =

area of upper triangle + area of side triangle + area of rectangle

<u>Therefore:</u>

Area of polygon = 21 + 10 + 28 = 59 in²

Hope this helps :)

How do you simplify on number 1?
Dennis_Churaev [7]
Okay. On the part that's not the whole number, see how the top number is BIGGER than the bottom? That means that it's not simplified. In order to make it simplified, you have to take a whole out of the pat that's not a whole number. Since the denominator is 12, the whole is 12/12. So, subtract it from the 13/12.

13/12-12/12=1/12

Now, since you found a whole inside of the fraction you have to add 1 to the whole number.
5+1=6

So, the answer is 6 1/12.

Thanks for the points!

lorasvet [3.4K]

Answer:

24

Step-by-step explanation:

This a special right triangle with angle measures of 30° 60° 90°

The side length that sees angle measure 30° is represented with a, the one that sees 90° is represented by 2a and the one that sees 60° is represented by a√2

AC sees angle B which has an angle measure of 60

(6√2)×(√2) = 24
