O A 8.4 ft
O B 9.3ft
O C111.8
O DI am totally lost

Which one is the answer?

Answer 1

Option B 9.3 ft

Explanation:

Proportions

We know the average height of a real cow is 4 feet 5 inches. Converting to inches it's

4*12+5=53 inches

The real chicken averages 13 inches, which means the cow's height is

53/13= 4.077 times the height of the chicken.

The same proportion must be applied to the statue of the chicken. Knowing the statue of the cow is 38 feet high, the statue of the chicken should be 4.077 times smaller, or

38/4.077 = 9.3 feet high

Answer 2

The size of chicken at the form would be 111.8 inches.

Explanation:

Given that,

The average height of cow = x1 = 4 feet 5 inches

x1 = 4 x 12 + 5 = 53 inches (12 inches in a feet)

The average height of chicken = y1 = 13 inches.

The height of cow statue at form = x2 = 38 feet

x2 = 38 x 12 = 456 inches

The height of chicken statue = y2 = ?

For this, the ratio of height in both the scenarios would be the same. Therefore,

x1/y1 = x2/y2

now, by putting the values

53/13 = 456/y2

y2 = (456x 13) / 53

y2 = 111.8 inches

Hence, the size of chicken at the form would be 111.8 inches.
