I am trying to find a simple formula for finding the surface area in square inches of an oval.
L x W x .80?
Thanks for any help!

Multiply the long side of the D, and the width, and then multiply by .75?
The formula for finding the square inch area of an oval is A = π * (a/2) * (b/2), where A is the area, π is the mathematical constant pi, a is the length of the oval's major axis, and b is the length of the oval's minor axis.
The major axis of an oval is the longest diameter, while the minor axis is the shortest diameter. To find these, you can measure the distance between the two opposite points on the oval's longest side for the major axis, and the distance between two opposite points on the oval's shortest side for the minor axis.
Yes, the formula can be used for any oval shape as long as you have the major and minor axis lengths. This includes both symmetrical and asymmetrical oval shapes.
The formula for finding the square inch area of an oval is different because it takes into account the oval's curved edges, unlike a regular rectangle or square which has straight edges. This is why the formula uses pi and the lengths of the major and minor axis instead of just the length and width.
Yes, the formula can be simplified by first dividing the major and minor axis lengths by 2, and then multiplying them by pi. This would result in the formula A = π * (a/2) * (b/2), which is the same as A = π * r1 * r2, where r1 is the radius of the major axis and r2 is the radius of the minor axis.
