Triangle
To find the area of a triangle, multiply the base by half the height.
Example: 50 x 20 = 1000 square metres

Circle
To find the area of a circle, multiply the radius (half the diameter) by itself and then multiply the answer by 3.1416.
Example: 25 x 25 x 3.1416 = 1963.5 square metres

Corrugated roofing
Most roofing has 63.5mm wide corrugations To find the total surface area, multiply the width of the corrugated sheet by 1.25 or add 25%
Example: 760 x 1.25 or 760 + 25% = 950
