Where the question says "oval", we'll assume it's referring to an "ellipse".(Our main reason for doing that is the fact that we know the formula for the areaof an ellipse, so the light is better over there.)The area of an ellipse is: (pi) x (1/2 the long axis) x (1/2 the short axis)Area = (pi) x (120) x (70) = 26,389.4 square metres. (rounded)
An ellipse is a two dimensional shape, so it does not have a "surface area", only an "area". Any ellipse has two radii, the major one and the minor one. We'll call them R1 and R2. The area of the ellipse then can be calculated with the function: a = πR1R2 You will notice that this is the same equation as the area for a circle. The circle is a special case though, because it is an ellipse in which both axes are the same length. In that case, R1 equals R2, so we can simply call it r and say: a = πr2

An oval is a general word that could have different shapes. If you squash a circle evenly, the new shape in math is called an ellipse, which has an oval shape. The formula for the area of a circle is Pi times the Radius of the circle squared. The radius is half the height of the circle and also half the width of the circle. The general formula for the area of an ellipse is Pi times half the height times half the width. So we say length A is half the height of an ellipse and length B is half the width of an ellipse. When A is equal to B you have a circle. When they are different you have an ellipse. So if you want the area of the circle to be the same as the area of the ellipse, then you have to keep the height times the width the same for the ellipse as it was for the circle. As you squash the ellipse further the width must stretch out more than the height gets pushed down. For example, a circle with radius of 1 inch would have the same area as an ellipse with height ½ inch and width 2 inches because 1 times 1 is equal to ½ times 2. Another ellipse with the same area could have height ¼ inch and width 4 inches.
Area = pi*a*b where a and b are the semi-major and semi-minor axes.
Area = pi*a*b where a and b are the semi-major and semi-minor axes.
pi x the minor radius x the major radius
To calculate the area of a half oval, you can use the formula A = (π * r^2) / 2, where A is the area and r is the radius of the oval. First, determine the radius of the half oval. Then, square the radius and multiply it by π. Finally, divide the result by 2 to find the area of the half oval.
the formula for finding the area of an ellipse is add it then multiply and subtract that is the final
That depends on the shape for which you want to calculate the area. A few of the most common ones: circle: a = πr2 square: a = l2 rectangle: a = l×w ellipse: a = π × r1 × r2 triangle: a = bh/2
An ellipse is 2-dimensional; it has no volume. The area of an ellipse is pi * A * B, where A and B are the lengths of its axes.

You know the formula for the area of a circle of radius R. It is Pi*R2. But what about the formula for the area of an ellipse of semi-major axis of length A and semi-minor axis of length B? (These semi-major axes are half the lengths of, respectively, the largest and smallest diameters of the ellipse--- see Figure 1.) For example, the following is a standard equation for such an ellipse centered at the origin: (x2/A2) + (y2/B2) = 1. The area of such an ellipse is Area = Pi * A * B , a very natural generalization of the formula for a circle!
