Fomula ni:

$$\text{Eneo} = \frac{1}{2}ab \sin(\theta)$$

ambapo $a$ na $b$ ni urefu wa pande, na $\theta$ ni pembe iliyopo kati ya pande hizo.

Tunapewa $a = 5$ cm, $b = 8$ cm, na $\theta = 30^\circ$.

$$\text{Eneo} = \frac{1}{2} \times 5 \text{ cm} \times 8 \text{ cm} \times \sin(30^\circ)$$

Tunajua kuwa $\sin(30^\circ) = \frac{1}{2}$.

$$\text{Eneo} = \frac{1}{2} \times 5 \text{ cm} \times 8 \text{ cm} \times \frac{1}{2}$$

$$\text{Eneo} = \frac{1}{2} \times 40 \text{ cm}^2 \times \frac{1}{2}$$ $$\text{Eneo} = 20 \text{ cm}^2 \times \frac{1}{2}$$ $$\text{Eneo} = 10 \text{ cm}^2$$

Eneo la pembetatu ni:

$$\text{10 cm}^2$$
