Abdul wants to hang a square poster that measure 1 1/2 feet on a side in the center of a 12-foot-long wall. How far from the end
densk [106]

Answer:

5.25 feets

Step-by-step explanation:

Given the question :

Abdul wants to hang a square poster that measure 1 1/2 feet on a side in the center of a 12-foot-long wall. How far from the end of the wall should abdul place the side of the poster?

Length of one side of Square poster = 1 1/2 Feets = 3/2 feets

Length of wall = 12 feets long

Since Abdul wants the poster to be centered in the wall; then the picture should be placed such that there must be equal space left on either side of the wall after hanging.

Hence, (12/2 - 1 1/2) = (6 - 0.75) feets

= 5.25 feets
