Area of a square
If s is the side-length of a square, the area of the square is:
What is the area?
Find the side length of the square.
Use this number in the formula.
| Area |
= side × side |
|
= 13 × 13 |
|
= 169 |
Now find the units. The lengths are measured in yards, so the area is measured in square yards.
| The area is |
169 |
square yards. |
What is the area when s=5?
