Calculate the area of various geometric shapes including squares, rectangles, triangles, and circles. Enter the required measurements and get instant results with formulas.
Given: Side = 5 cm
Solution:
A = s² = 5² = 25 cm²
Given: Length = 8 m, Width = 3 m
Solution:
A = l × w = 8 × 3 = 24 m²
Given: Base = 10 cm, Height = 6 cm
Solution:
A = ½ × b × h = ½ × 10 × 6 = 30 cm²
Given: Radius = 4 in
Solution:
A = πr² = π × 4² = 16π ≈ 50.27 in²
Given: Garden bed 12 ft × 8 ft
Solution:
A = 12 × 8 = 96 ft² (for landscaping)
Area is the amount of space inside a two-dimensional shape. It is measured in square units such as square meters (m²), square centimeters (cm²), or square feet (ft²).
| Shape | Formula | Variables |
|---|---|---|
| Square | A = s² | s = side length |
| Rectangle | A = l × w | l = length, w = width |
| Triangle | A = ½ × b × h | b = base, h = height |
| Circle | A = πr² | r = radius |
