a wooden board is 3 yards 1 foot long . which show an equivalent length
10 feet
L = 3yds * 3ft/yd + 1ft = 10 ft.

To find an equivalent length, we need to convert yards and feet into a common unit, either yards or feet. Let's convert the length into feet.
1 yard is equal to 3 feet, so 3 yards would be 3 * 3 = 9 feet.
1 foot is equal to 1 foot, so we add the given 1 foot.
Therefore, the wooden board is equivalent to 9 + 1 = 10 feet long.
