Estimate the length of the red and green pencils if the length of the brown pencil is 12 inches and yellow pencil is 4 inches.

The correct option is A 11 inches, 5 inches
Length of brown pencil = 12 inches
The length of the red pencil is a little less than the brown one.
So, estimated length of red pencil = 11 inches
Length of yellow pencil = 4 inches
The length of the green pencil is a little more than the yellow one.
So, estimated length of green pencil = 5 inches
Hence, the estimated length of the red and green pencil is 11 inches and 5 inches, respectively.
