Find the area of each complex figure.

8. 10 ft^2

9. 64 km^2

10. 245 m^2

Step-by-step explanation:

8.

the square on the right is 1x1 thus has an area of 1

the center rectangle is 2x3 thus has an area of 6

the triangle on the left is 2x3/2 thus has an are of 3

9.

the squares are identical so the area of one of the x2 will get you the answer

8x4x2=64

10.

10x7=70

9x14=126

7x14/2=49

70+126+49=245

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
