Answer:
1.6 m and 1.8 m.
Step-by-step explanation:
Given that Mercus height = 1.5 m.
Marcus sister Carol height = 1.5+0.1 (since she is taller than Marcur by 0.1')
= 1.6 metres.
Thus Marcus sister is 1.6metres tall.
Coming to father's age, given that father is 0.2 meter taller than Carol.
Hence father's height = height of Marcus sister +0.2
= 1.6+0.2 = 1.8 metres.
