what is the formala of area????????????????????????????????????????????????????????
+808 Would be very helpful if you could specify what geometric object you would like to know the area of.
Nontheless here are a few formula for the area of polygons and circles:
square: A = s2, s: length of one side
rectangle: A = lw, (length * width)
circle: A = pi * r2, r: radius
triangle: A = bh/2, b: base, h: height
quadrilateral: A = pq sin t, (p and q are the length of the diagonals, and t is the angle between them)
parallelogram A = bh (base * heigth)
rhombus: A = pq/2 (p and q are the length of the diagonals)
trapezoid: (a + b)h/2 (a and b are the length of the parallel sides, h is the heigth)
ellipse: pi * ab, (a and b are the semi-major and the semi-minor axes)
