Answer:
96 inches
Step-by-step explanation:
Use perimeter to measure the outside edges of something.
(30 × 2) + (18 × 2)
30 + 30 + 18 + 18
96 inches of the ribbon would be needed
In order to determine the inches of ribbon needed, we are to calculate the perimeter of the board
The board is in the shape of a rectangle, so we would use the formula for the perimeter of a rectangle to determine the length of the ribbon needed.
Perimeter of a rectangle = 2 x (length + breadth)
2 x (30 + 18) = 96 inches
