Respuesta :
1 foot = 12 inches
Height of Jacob = 5 feet 6 inches = 5 *12 + 6 = 66 inches
Jacob's shadow = 3 feet = 36 inches
giraffe's shadow = 5 feet 9 inches = 5 * 12 + 9 = 69 inches
by the ratio and proportion
∴ Height of Jacob/Jacob's shadow = Height of giraffe/giraffe's shadow
∴ 66/36 = Height of giraffe/69
∴ Height of giraffe = 69 * 66/36 = 126.5 inches = 10 feet 6.5 inches
Height of Jacob = 5 feet 6 inches = 5 *12 + 6 = 66 inches
Jacob's shadow = 3 feet = 36 inches
giraffe's shadow = 5 feet 9 inches = 5 * 12 + 9 = 69 inches
by the ratio and proportion
∴ Height of Jacob/Jacob's shadow = Height of giraffe/giraffe's shadow
∴ 66/36 = Height of giraffe/69
∴ Height of giraffe = 69 * 66/36 = 126.5 inches = 10 feet 6.5 inches
The height of the giraffe whose shadow is 5 feet 9 inches at the same time will be 10 feet and 6.5 inches.

Let x be the hieght of the giraffe. Then we have
The ratio will remain constant.
x / 5.75 = 5.5 / 3
x = 10.54
x = 10 feet 6.5 inches
