Sum of 8 numbers = 38.4 × 8 = 307.2

Sum of 7 numbers = 39.2 × 7 = 274.4

Therefore 8th number = 307.2 – 274.4 = 32.8

Let father's age be x year and son's age be y year.

According to question,

2(x+y) = 8y _______(I)

and = 28

or, x+y = 56 years__________(II)

From equation (I) and (II)

8 y = 112

y = 14 years, hence x = 42 years

2(l+b) = 46

(l + b)²  = (23)2 

(l²  + b² ) +2lb = 529

17²  + 2lb = 529 => lb = 120

Area = l × b = 120 cm2
