Area of Plane Shapes

	Triangle مثلث Area = ½ b × h b = base h = vertical height		Square مربع Area = a^2 a = length of side
	Rectangle مستطيل Area = w × h w = width h = height		Parallelogram متوازي أضلاع Area = b × h b = base h = vertical height
	Trapezoid (US) شبه منحرف Trapezium (UK) Area = ½ (a+b) × h h = vertical height		Circle دائرة Area = π r^2 Circumference=2π r r = radius
	Ellipse بيضاوي Area = π a b		Sector قطاع Area = ½ r^2θ r = radius θ = angle in radians

Here is an example:

Example: What is the area of this rectangle?

The formula is:

Area = w × h
w = width
h = height

w = 5 cm and h = 3 cm, so:

Area = 5 × 3 = 15 cm²
