5. André the Giant is 7 ft. 4 in.tall. Determine his height to the nearest centimetre. 6. Duc rode his bike in a marathon for 35 miles. Sally walked 50km. Who travelled further? Justify your answer. 7. Petey is building a fence around his rectangular garden. His garden measures 20n 2in by 18ff 5in. Material can only be sold in whole numbers of yards.If it costs 4.75 per yard, what will the cost of nceded material be? [2] [1]

## Step 1: Converting Feet and Inches to Centimeters<br /><br />### André's height is 7 ft 4 in. First, convert feet to inches: 7 ft × 12 in/ft = 84 in. Then, add the remaining inches: 84 in + 4 in = 88 in. Finally, convert inches to centimeters: 88 in × 2.54 cm/in = 223.52 cm. Rounding to the nearest centimeter gives 224 cm.<br /><br />## Step 2: Comparing Distances in Different Units<br /><br />### Duc rode 35 miles. Sally walked 50 km. To compare, convert miles to kilometers: 35 miles × 1.609 km/mile ≈ 56.315 km. Since 56.315 km > 50 km, Duc traveled further.<br /><br />## Step 3: Calculating Fence Perimeter and Cost<br /><br />### The garden is 20 ft 2 in by 18 ft 5 in. Convert dimensions to inches: 20 ft × 12 in/ft + 2 in = 242 in and 18 ft × 12 in/ft + 5 in = 221 in. The perimeter is 2 × (242 in + 221 in) = 926 in. Convert inches to yards: 926 in × (1 yd / 36 in) ≈ 25.72 yds. Since material is sold in whole yards, round up to 26 yards. The total cost is 26 yds × $4.75/yd = $123.50.
