Answer 1

The possible length of the unit in centimeters given a perimeter of 29 meters is 725 centimeters

Perimeter of a square

• Perimeter of the square = 29 meters

convert to centimeters

• 1 meter = 100 centimeters
• 29 meters = 2900 centimeters

Perimeter of a square = 4a

where,

• a = side length

Perimeter of a square = 4a

2900 = 4a

divide both sides by 4

a = 2900/4

a = 725 centimeters

Therefore, the possible length of the unit in centimeters given a perimeter of 29 meters is 725 centimeters
