Question

Lisa wants to place a border around a square bulletin board in her classroom. How long should the border be if one of the sides of the bulletin board is 10 ft?

Answer 1

The length of the border for a square bulletin board with a 10 ft side is 40 ft.

Step-by-step explanation:

To find the length of the border for a square bulletin board, we need to calculate the perimeter of the square. The perimeter is simply the sum of the lengths of all four sides. Since all sides of a square are equal in length, we can multiply the length of one side by 4 to find the perimeter.

In this case, since one side of the square bulletin board is 10 ft, the border length would be 10 ft x 4 = 40 ft.
