12 x 24 oval
half base multiply height. 1/2BasexHeight
length x width = area
You can calculate the area of any quadrilateral by dividing it into two triangles and summing their areas. A triangle's area is found by multiplying the base by the half of the height (when height measured perpendicular to the base)
You take half the area of a circle in square feet. The formula is: 1/2 * pi * (radius)2
Half of the height times half of the width time pi (3.1415926535897)
half of breath times half of length * * * * * times pi
An oval, or more technically an ellipse, has a long ( major) axis and short (minor axis). If major axis length is a and minor length is b, then area, A is A = pi*a*b /4 where and so the area of half an oval is pi*a*b/8
the formula for calculating the surface area of an oval is A = Pi * a * b where a & b are the semimajor(half the long) and semiminor(half the short) axes
A = Pi * a * b where a & b are the semimajor(half the long) and semiminor(half the short) axes
Since it's an oval and not a circle, you would need the 'long' and 'short' diameters to be able to calculate area, which then with the depth, you can calculate volume.
18 x 33 divided by 2
12 x 24 oval
The answer depends on what characteristic of a half circle you want to calculate: its area or perimeter or something else.
you split your shape in half, (The rectangle and the triangle), by putting a line through it and then calculate the area of the rectangle and then calculate the area of the triangle, half the area of the triangle then add the area of the triangle and the rectangle together!Then you should have your answer!
An oval,or more technically an ellipse, has a long ( major) axis and short (minor axis). If major axis length is a and minor length is b, then area, A is A = pi x a x b /4 where pi = 3.14 (approx)
It depends on the shape whose area you wish to calculate. Different shapes have different formulae.
