Calculate area in square yards for rectangles, triangles, and circles — enter dimensions in feet, meters, inches, or yards.
Calculate area in square yards for rectangles, triangles, and circles.
Formula: Area = Length × Width
Formula: Area = ½ × Base × Height
Formula: Area = π × r²
Three simple steps to calculate area for any shape in square yards.
Click the Rectangle, Triangle, or Circle tab above to select the shape you want to calculate. Each shape uses a different formula optimized for accurate results.
Type the dimensions into the input fields. For rectangles, enter length and width. For triangles, enter base and height. For circles, enter the radius. Select your unit from the dropdown.
The calculator instantly shows the area in both square yards (yd²) and square feet (ft²). For example, a rectangle 15 ft × 12 ft = 180 ft² ÷ 9 = 20 square yards.
Understanding area formulas for common geometric shapes.
Rectangle: Area = Length × Width. Multiply both dimensions in yards. If in feet, multiply and divide by 9 to get square yards. Example: 10 ft × 8 ft = 80 ft² ÷ 9 = 8.89 yd².
Triangle: Area = ½ × Base × Height. Measure the base and the perpendicular height, convert to yards, and apply the formula. Example: base 12 ft, height 9 ft = ½ × 12 × 9 = 54 ft² ÷ 9 = 6 yd².
Circle: Area = π × r². Measure the radius (half the diameter), convert to yards, then square it and multiply by π (3.14159). Example: radius 6 ft = 6/3 = 2 yd → π × 4 = 12.57 yd².
All three formulas are built into this calculator. Simply select the shape, enter your dimensions in any unit, and the tool handles the conversion automatically.
Common questions about calculating area for different shapes.
Multiply the length by the width (both in yards) to get the area in square yards. If your measurements are in feet, multiply length × width and divide by 9.
Area = ½ × Base × Height. Convert base and height to yards first, then apply the formula. If in feet, calculate ½ × base × height and divide by 9.
Area = π × r² where r is the radius in yards. If your radius is in feet, divide by 3 to convert to yards, then square it and multiply by π (3.14159).
Yes, our calculator supports feet, yards, meters, and inches. Enter your measurements in any unit and the calculator converts automatically to square yards.
This calculator supports three shapes: rectangles (length × width), triangles (½ × base × height), and circles (π × radius²). All results are displayed in square yards and square feet.
