Can you plz solve 6-8 on this pic you have to find the area for it plz

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 2 shapes, A rectangle and a square

                  ████████                                           ◣

rectangle: ████████            triangle:               █◣

                   ████████                                          ██◣

rectangle:

to calculate a rectangle's area: multiply the lengths of the width and height:

████████= width  8           █

                                                █    =height 3

                                                █

now substitute the values of W and H:

rectangle area = 24

Triangle:

to find the area of a triangle, multiply the width and height and divide by two:

◣ + ◣ = █         0.5 + 0.5 = 1

                                                █    

███=width   3                         █ =height  3

                                                █    

now substitute W and H

Triangle area: 4.5

Now add the Rectangle Area To the triangle Area:

4.5 + 24 = 28.5

Final

AREA =2 8.5

hope this helps!

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
