Solution
Perimeter of a square = (4 × side) units
Area of a square = (side × side) unit2
Area = s × s unit2
49 = s × s square feet
s2 = 72
s = 7 feet
Perimeter = 4 × s unit
= 4 × 7 feet
= 28 feet
Perimeter = 28 feet
Completing the unknown values in the table
| Side | Perimeter | Area |
| 7 feet | 28 feet | 49 sq.feet |
