Round Areas

Method: Space = πr2

Measure the radius, which is the gap from the midpoint of the house to the sting. The radius is half the diameter — or the size of a straight line that passes by way of the middle of the circle.

Subsequent, sq. the radius and multiply it by pi (π), or 3.14.

Triangular Areas

Method: Space = ½bh

This system works with proper triangles, which have one 90-degree angle. In case your house isn’t already a proper triangle, break it into two proper triangles for the needs of measuring.

For every proper triangle, multiply the lengths of the straight sides — the bottom and top. Then, divide by two. With a number of triangles, add the values for the whole sq. footage.
