I think the answer is D) 24/25.
Again sorry if its wrong!!
The answer for number 3 is 96.7 if you want the work shown I would recommend you to download the app Socratic and for number six you multiply.75x14 then also multiply.35x7 then add add up the answers which will be 12.95 then you subtract that from 15 the answer is $2.05
Answer:
Figure 3: 28.5 units²
Figure 4: 33 units²
Figure 5: 25 units²
Figure 6: 30 units²
Figure 7: 25 units²
Figure 8: 32 units²
Reasons:
Figure 3 consists of<u> </u><u>2</u> shapes, A <u>rectangle </u>and a <u>square</u>
████████ ◣
rectangle: ████████ triangle: █◣
████████ ██◣
rectangle:
to calculate a <em><u>rectangle's </u></em>area: multiply the lengths of the width and height:
████████= width 8 █
█ =height 3
█

now substitute the values of W and H:

<u>rectangle area = </u><u>24</u>
Triangle:
to find the area of a <u><em>triangle</em></u>, multiply the width and height and divide by two:
◣ + ◣ = █ 0.5 + 0.5 = 1
█
███=width 3 █ =height 3
█

now substitute W and H


<u>Triangle area:</u><u> 4.5</u>
Now add the Rectangle Area To the triangle Area:
4.5 + 24 = 28.5
Final answer:
AREA =2 8.5
hope this helps!
