Answer:
Area of ABC = 30 cm² and AD = 4.61cm
Step-by-step explanation:
Area of ABC
=1/2 × AC × AB
=0.5 × 12 × 5
=30 cm²
By Pythagoras Theorem,
(AC)² + (AB)² = (BC)²
(12)² + (5)² = (BC)²
(BC)² = 144 + 25
(BC)² = 169
BC = 13 cm
Area of ABC = Area of ABC
30 = 1/2 ×AD ×BC
60 = AD × 13 (Multiplying by 2 on both the sides)
AD = 60/13
AD = 4.61 cm
