Display board measurements = 10ft by 6ft So all the sides would be 10ft, 10ft, 6ft, 6ft Add them all together= 32ft Ribbon length would need to be 32ft long
To solve, you have to find the perimeter of the board since you are decorating it. The formula for that is P = (L x 2) + (W x 2) P = (10 x 2) + (6 x 2) P = 20 + 12 Perimeter = 32 ft. Sydney needs 32 ft. of ribbon to border the board.
