1 yard = 3 feet
1 feet = 12 inches
1 yard = 3 x 12 = 36 inches
We need to find 7 yard + 2 feet = ? inches
Then change the yard to the inch and the feet to the inch, then add them
7 yards = 7 x 36
7 yards = 252 inches
2 feet = 2 x 12
2 feet = 24 inches
Sum them up
7 yd + 2 ft = 252 + 24
7 yd + 2 ft = 276 inches
