Final answer:
To find the width of the display board, use the formula for the area of a rectangle and solve for the width.
Step-by-step explanation:
To find the width of the display board, we can use the formula for the area of a rectangle: area = length × width.
We are given that the area is ft² and the length is 2 ft.
We can plug these values into the formula and solve for the width:
area = length × width
ft² = 2 ft × width
ft² = 2 ft × width
ft² = 2w
Now, to solve for w, we divide both sides of the equation by 2:
ft²/2 = 2w/2
ft²/2 = w
So, the width of the display board is ft.
