The correct Answer is:
To find the area of the parallelogram with adjacent sides of lengths 6 cm and 8 cm, and an angle of 30 degrees between them, we can use the formula for the area of a parallelogram: \[ \text{Area} = \text{base} \times \text{height} = a \times b \times \sin(\theta) \] where: - \( a \) and \( b \) are the lengths of the adjacent sides, - \( \theta \) is the angle between the sides. ### Step 1: Identify the values Here, we have: - \( a = 6 \) cm (one side) - \( b = 8 \) cm (the adjacent side) - \( \theta = 30^\circ \) ### Step 2: Substitute the values into the formula Now, substitute the values into the area formula: \[ \text{Area} = 6 \times 8 \times \sin(30^\circ) \] ### Step 3: Calculate \(\sin(30^\circ)\) We know that: \[ \sin(30^\circ) = \frac{1}{2} \] ### Step 4: Substitute \(\sin(30^\circ)\) into the equation Now substitute \(\sin(30^\circ)\) back into the area formula: \[ \text{Area} = 6 \times 8 \times \frac{1}{2} \] ### Step 5: Simplify the expression Now simplify the expression: \[ \text{Area} = 6 \times 8 \times 0.5 = 6 \times 4 = 24 \text{ cm}^2 \] ### Final Answer Thus, the area of the parallelogram is: \[ \text{Area} = 24 \text{ cm}^2 \] ---
