Answer:

26 1-foot squares of silver paper.

Step-by-step explanation:

The dimensions of the bulletin board are 6.5 feet by 4 feet.

To determine how many squares of silver paper she needs to but, we first determine the area of the bulletin board.

Area of the board =6.5 X 4= 26 Square feet

Therefore, Mrs Golden needs to buy 26 1-foot squares of silver paper.

There will be no pieces left over as there is no decimal or fractional value in the area of the bulletin board.
