The area of a triangle is calculated using the formula: Area = (base * height) / 2.
Plugging in the given values, we have:
Area = (20 * 12) / 2
Area = 240 / 2
Area = 120 square inches
Therefore, the correct answer is 120 square inches.

The area of a circle is calculated using the formula: Area = π * r^2, where π is a constant value approximately equal to 3.14159 and r is the radius of the circle.
Plugging in the given value, we have:
Area = 3.14159 * (7)^2
Area = 3.14159 * 49
Area ≈ 153.938 square inches
Rounding to the nearest tenth, the area of the circle is approximately 153.9 square inches.
Therefore, the correct answer is 153.9 square inches.
