Calculate the area and perimeter of a stadium.
This calculator uses feet and or inches for measurements.

A stadium here is an oval shape consisting of a rectangle with two semi-circles at the opposing ends.

If the diameter length is equal to the overall length you are calculating for a circle area and circumference!!

A = 𝝅/4D²+LD
P = 𝝅D+2L
where A is the area of the kite
D the diameter length
L the overall length minus the diameter
P the perimeter of the kite

one square foot ( ft²) = 144 square inches (in²)
one square inch (in²) = 0.00694444444444443 square feet (ft²)
one square foot ( ft²) = 0.09290304 square metres (m²)
square inch (in²) = 0.00064516 square metres (m²)
