| A sheep farmer has a square shaped paddock of 25 hectares. Find the perimeter of the paddock. |
| 25 hectares = 25 × 10,000 = 250,000m2 |
there are 10,000m2 in 1 hectare convert to m2 by multiplying by 10,000 |
| ss = 250,000 |
since the area of a square is A = s2, 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 |
