1 yd = 3 ft area = ½ × (sum bases) × height → area = ½ × (5 ft + 3½ yd) × 7 ft = ½ × (5 ft + (3½ × 3) ft) × 7 ft = ½ × (5 + 10½ ft) × 7 ft = 54¼ sq ft
Which is greater? 21 ft or 7 yd
7 yd 1 ft - 5 yd 2 ft = 22 ft - 17 ft = 5 ft = 1 yd 2 ft.

1 yard = 3 feet. So 9 yd 7 ft - 6 yd 8 ft = 2 yd 2ft
Convert to the same units, then a comparison can be made: Converting both to feet: 1 yd = 3 ft → 2 yd = 2 × 3 ft = 6 ft < 7 ft → 2 yards is less than 7 ft Alternatively, converting both to yards: 3 ft = 1 yd → 7 ft = 7 ÷ 3 yds = 2 1/3 yds > 2 yds → 2 yards is less than 7 ft.

1 ft = 12 in 36 in = 1 yd → 7 ft 7 in = 7 x 12 + 7 in = 91 in → 91 in = 91 / 36 yd = 2 yd 19/36 in ≈ 2.53 yd

3 yd 2 ft - 1 ft 5 in = 9 ft + 2 ft - 1 ft - 5 in = 10 ft - 5 in = 9 ft 7 in = 3 yd 7 in
