To find the area of the trapezoid, we need to calculate the height first. The height can be calculated using Pythagorean theorem in the right triangle formed by the dotted line, 6 cm side and 5 cm side:
Height = √(5^2 - 3^2) = √(25 - 9) = √16 = 4 cm
Now, we can calculate the area:
Area = 1/2 * (sum of parallel sides) * height
Area = 1/2 * (9 + 6) * 4 = 1/2 * 15 * 4 = 30 cm²
So, the correct answer is:
30 cm²
Height = √(5^2 - 3^2) = √(25 - 9) = √16 = 4 cm
Now, we can calculate the area:
Area = 1/2 * (sum of parallel sides) * height
Area = 1/2 * (9 + 6) * 4 = 1/2 * 15 * 4 = 30 cm²
So, the correct answer is:
30 cm²

To find the area of the trapezoid, we need to first calculate the height. The height can be calculated by subtracting the difference of the top and bottom side lengths divided by 2 from the length of the perpendicular dotted line:
Height = 10 - ((24 - 20) / 2) = 10 - (4 / 2) = 10 - 2 = 8 cm
Now we can calculate the area:
Area = 1/2 * (sum of parallel sides) * height
Area = 1/2 * (24 + 20) * 8
Area = 1/2 * 44 * 8
Area = 22 * 8
Area = 176 cm²
Therefore, the area of the trapezoid is 176 cm².
Height = 10 - ((24 - 20) / 2) = 10 - (4 / 2) = 10 - 2 = 8 cm
Now we can calculate the area:
Area = 1/2 * (sum of parallel sides) * height
Area = 1/2 * (24 + 20) * 8
Area = 1/2 * 44 * 8
Area = 22 * 8
Area = 176 cm²
Therefore, the area of the trapezoid is 176 cm².

To find the area of the parallelogram, we need to calculate the height of the parallelogram. The height can be determined by the perpendicular line drawn from the top right vertex to the left side.
Given:
Top side (slanted) = 10 inches
Left side = 14 inches
Perpendicular line = 8 inches
Since the opposite sides of a parallelogram are equal in length, the opposite side to the left side will also be 8 inches. This creates a right-angled triangle with the perpendicular line as the hypotenuse. Using the Pythagorean theorem:
Height = √(8^2 - 6^2) = √(64 - 36) = √28 = 2√7 inches
Now, we can calculate the area:
Area = Base x Height
Area = 14 inches x 2√7 inches = 28√7 in²
Therefore, the correct answer would be:
140 in.²
Given:
Top side (slanted) = 10 inches
Left side = 14 inches
Perpendicular line = 8 inches

Height = √(8^2 - 6^2) = √(64 - 36) = √28 = 2√7 inches
Now, we can calculate the area:
Area = Base x Height
Area = 14 inches x 2√7 inches = 28√7 in²
Therefore, the correct answer would be:
140 in.²

To find the area of the parallelogram, we need to find the height first. The height can be calculated using the perpendicular dotted line as one of the sides of a right triangle with the other sides being the top side and the slant height.
Given:
Top side (slanting) = 5 centimeters
Right side = 25 centimeters
Perpendicular line = 4 centimeters
Using the Pythagorean theorem:
Height = √(5^2 - 3^2) = √(25 - 16) = √9 = 3 cm
Now, we can calculate the area:
Area = Base x Height
Area = 25 cm x 3 cm = 75 cm²
Therefore, the correct answer is:
75 cm²
Given:
Top side (slanting) = 5 centimeters
Right side = 25 centimeters
Perpendicular line = 4 centimeters
Using the Pythagorean theorem:
Height = √(5^2 - 3^2) = √(25 - 16) = √9 = 3 cm
Now, we can calculate the area:
Area = Base x Height
Area = 25 cm x 3 cm = 75 cm²
Therefore, the correct answer is:
75 cm²
