GEOMETRY+ PYTHAGORAS THEOREM .

 \huge\mathbb{\red A \pink{N}\purple{S} \blue{W} \orange{ER}}

(a) the area of the ∆ ABC,

area =  \frac{1}{2} base \times height \\ area =  \frac{1}{2}  \times 12 \times 5 \\ area = 6 \times 5 \\ area = 30 \:  \: cm \:  \:  \: ans

(b) the length of AC and

third \: side =  \sqrt{ {5}^{2} +  {12}^{2}}

third \: side \:  = AC =  \sqrt{144 + 25}  \\ AC =  \sqrt{169}  = 13 \\ ac = 13 \:  \: cm \:  \: ans \:
