To solve this problem, we need to know the formulas for the areas of each of these shapes. The formula for the area of a circle is πr², the area of a rectangle is b * h, the area for a square is s², and the area for a triangle is 0.5bh. Now we can solve.

1) This is a circle, so the area is πr² = π(6)² = 36π square feet

2) This is a square, so the area is s² = 12² = 144 square yards

3) This is a rectangle, so the area is b * h = 6 * 14 = 84 square inches

4) This is a rectangle, so the area is b * h = 7 * 3 = 21 square inches

5) This is a circle, so the area is πr² = π(4)² = 16π square feet

6) This is a triangle, so the area is 0.5bh = 0.5 (8 * 8) = 0.5 * 64 = 32 yd.²

7) This is a triangle, so the area is 0.5bh = 0.5 (5 * 10) = 50 * 0.5 = 25 yd.²

8) This is a rectangle, so the area is b * h = 10 * 2 = 20 in²

9) This is a square, so the area is s² = 9² = 81 ft²
