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

                                                █

area=w(h)

now substitute the values of W and H:

8(3)=24

<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

                                                █    

               

area=\frac{w(h)}{2}

now substitute W and H

area=\frac{3(3)}{2}

area\frac{9}{2}

<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!
