Hint:
Unitary method: The unitary method is a method in which we find the value of a unit and then the value of a required number of units. For example, If 10 apples cost is 100 rupees, 1 apple will cost 10 rupees and if we are asked to find the cost of 100 apples, we can find it by multiplying 100 with the cost of 1 apple.
The correct answer is: 133 cm
The ratio of the height of Walter and William is given as 7 : 8 or we can write

= 
Height of Walter = 
= 133 cm
