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 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 answer:
AREA =2 8.5
hope this helps!
