Answer:
The area of a triangle is the space contained within its 3 sides. To find out the area of a triangle, we need to know the length of its three sides. The sides should be measured in feet (ft) for square footage calculations and if needed, converted to inches (in), yards (yd), centimetres (cm), millimetres (mm) and metres (m). The formula:
Square feet to square meters: multiply ft² by 0.092903 to get m²
Square yards to square feet: multiply yd² by 9 to get ft²
Square feet to square yards: multiply ft² by 0.11111 to get yd²
Square yards to square meters: multiply yd² by 0.8
Step-by-step explanation:
A regular polygon of "n" sides has "n" Lines of Symmetry
