Answer
$\approx 19.10$ square unit
Work Step by Step
The triangle has sides of length 10 unit and 22 unit , with included angle $10^{0}$. Therefore-
Area, (A) of the triangle,
A = $ \frac{1}{2}$ a b $\sin \theta$
= $ \frac{1}{2} \times a\times b \times \sin \theta$
= $ \frac{1}{2} \times 10\times 22 \times \sin 10^{0}$
= $\frac{1}{2}\times220\times0.173648$
$\approx 19.10$ square unit
