What is the area of a rectangle with length 8 cm and width 5 cm?

The area of a rectangle is calculated by multiplying its length and width. In this case, the area of a rectangle with a length of 8 cm and a width of 5 cm would be 40 square centimeters.

What is the area of a circle with a radius of 3.5 cm?

The area of a circle with a radius of 3.5 cm is approximately 38.48 square centimeters, calculated using the formula for the area of a circle: A = ?r^2, where A is the area, ? is approximately 3.14, and r is the radius (3.5 cm in this case).

What is the area of a triangle with base 9 cm and height 6 cm?

To find the area of a triangle, you multiply the base by the height and divide the result by 2. Therefore, the area of a triangle with a base of 9 cm and a height of 6 cm is 27 square centimeters.

What is the area of a parallelogram with base 10 cm and height 7 cm?

To find the area of a parallelogram, you can multiply the base by the height. In this case, the base is 10 cm and the height is 7 cm. Therefore, the area of the parallelogram is 10 cm x 7 cm = 70 square cm.

What is the area of a square with side length 12 cm?

The area of a square with side length 12 cm is 144 square centimeters.

What is the area of a trapezoid with bases measuring 5 cm and 9 cm, and a height of 4 cm?

The area of a trapezoid is calculated by multiplying the average of the bases by the height. In this case, the average of the bases is (5+9)/2 = 7 cm. Therefore, the area of the trapezoid is 7 cm * 4 cm = 28 cm².

What is the area of a semi-circle with a diameter of 12 cm?

The area of a semi-circle can be calculated as half the area of a circle. The formula to calculate the area of a circle is A = ?r², where r is the radius (which is half the diameter). In this case, the diameter is 12 cm, so the radius is 12 cm / 2 = 6 cm. Plugging this radius value into the formula gives us the area of the circle as 3.14 * 6² = 113.04 square cm. Since the semi-circle is half of that, the area of the semi-circle with a diameter of 12 cm is 56.52 square cm.

What is the area of an irregular shape with no specific formula, but given measurements of side lengths and angles?

To find the area of an irregular shape with no specific formula, given measurements of side lengths and angles, you can divide the shape into smaller familiar shapes like triangles, rectangles, or trapezoids. Then calculate the individual areas of these smaller shapes using their respective formulas and add them up to find the total area of the irregular shape. This method is called the composite figures method and can be used to find the area of irregular shapes with no predefined formula.

What is the area of a pentagon with side lengths of 6 cm each?

To find the area of a regular pentagon, we can use the formula: Area = 1/4 * ?(5(5 + 2?5)) * s^2, where s is the length of one of the sides. Plugging in the side length of 6 cm, we get: Area = 1/4 * ?(5(5 + 2?5)) * 6^2 = 54?5 cm^2. Therefore, the area of the pentagon with side lengths of 6 cm each is approximately 119.97 square centimeters.

What is the area of a hexagon with an apothem of 5 cm and a side length of 8 cm?

The area of a hexagon can be calculated using the formula 1/2 * apothem * perimeter. Substituting the values, the area of the hexagon with an apothem of 5 cm and a side length of 8 cm would be 1/2 * 5 cm * (6*8 cm) = 1/2 * 5 cm * 48 cm = 120 square cm.
