A sheep farmer has a square shaped paddock of 25 hectares. Find the perimeter of the paddock. | |
25 hectares = 25 × 10,000 = 250,000m^{2} | there are 10,000m^{2} in 1 hectare convert to m^{2} by multiplying by 10,000 |
s^{s} = 250,000 | since the area of a square is A = s^{2}, form an equation and solve for s, the side length |
s = √250,000 | square root both sides |
s = 500m | solve for s |
Perimeter = 4 × 500m = 2000m | Perimeter of a square is P = 4s |
