Answers
Answer:
Answer:
1) The distribution is fair
2) The value depicted here is caring nature, impartialness
Explanation:
There is a figure that goes with this question. The figure is attached.
ΔABD is a right angled triangle
∴ AB² + BD² = AD²
or BD² = AD² - AB²
or BD² = 10² - 6²
or BD² = 100 - 36
or BD² = 64
or BD = 8
Area of ΔABD = 1/2 × 6 × 8 = 24 cm²
Area of ΔBCD can be calculated using Heron's formula
Area = 8(8-a)(8-b)(8-c)
semi-parameter s = (5+5+8)/2 = 9
Area = {9(9-8) (9-5)9(9−8)(9−5)
= /sq{9(4)(4) = 12 cm²
ΔBCD forms Part-I and ΔABD forms Part-II
Part-2 is equally divided between driver and gardener so they both get the chocolate of area 12 cm²
Thus the distribution is fair
The lady has distributed the chocolate among the three indiscriminately. This shows that she cares for all three and there is no biased.
