Show the working
- A = ½ × p × q × sin θ, θ = 30° (the angle between the diagonals)
- Area = 15 ft²
How to use it
Enter the base and height. Enter the side a, side b and angle. Enter the diagonal p, diagonal q and angle.
Enter the measurements (decimals, fractions such as 3/4, or mixed numbers such as 1 1/2) and, if you like, their unit; the answer is then also given in other units. Show the working gives the formula.
Key facts
A = b h = a b sin α = ½ p q sin θ
Choosing a method
Use the height when you can measure straight across; otherwise two sides and the angle between them.
Questions
What is the area with sides 8 and 5 at 60°?
20√3 ≈ 34.64101615.
And with base 30 and height 20?
600.
Formulas
A = b h = a b sin α = ½ p q sin θ
