Question

The length of the bird's head is 9 centimeters. His tail is equal to the size of his head plus half of the size of his body. His body is the size of his head plus his tail. What is the length of the bird?​

Answer 1

72cm. Th head is 9cm. The tail is 18 + 9= 27cm. The body is 9 + 18 + 9= 36cm. 9 + 27 + 36= 72cm.

Answer 2

Let's assume the length of the bird's body is B centimeters.

According to the given information:

• The length of the bird's head is 9 centimeters.
• The length of the bird's tail is equal to the size of his head plus half of the size of his body, which is 9 + (0.5 * B) centimeters.
• The length of the bird's body is the size of his head plus his tail, which is 9 + (9 + 0.5 * B) centimeters.

To find the total length of the bird, we need to add up the lengths of the head, tail, and body:

Total length = head length + tail length + body length Total length = 9 + (9 + 0.5 * B) + (9 + 0.5 * B) centimeters

Simplifying the expression: Total length = 27 + B centimeters

Therefore, the length of the bird is 27 + B centimeters.
