Area is length x width.
Assuming the napkin is square, the side is sqrt(605.16) = 26.4 in whatever units.
how do you find area of a square that has sides of length 96 inches
because you do
HOW TO FIND THE AREA OF A SQUAREmust x all sides
The only way to find the area is to have two sides to multiply them together unless you have the hypotenuse.
The formula to find the area of an octagonal pyramid is area of base plus area of sides.
Its not a triangle if it has only two sides.
Multiply the sides
Area = 0.5*(sum of parallel sides)*height
find area of all sides then add them
Length of side = square root of area
Area = 0.5*(sum of parallel sides)*height
You multiply the two sides the object in order to find the square feet of an area
