To find the area of compound shapes we must divide the compound shape into basic shapes and find the area of each of the basic shapes and add them together Our final answer must be in square units e g square centimetres cm 2 square meters m 2 square feet ft 2 etc Given Segments Points Triangle Quadrilateral Circle Parallels Compound Shapes Calculator find pentagon area given square area and triangle area
To find the area of a right angled triangle you need to multiply the two perpendicular sides together and halve the result So the area of a right angle triangle x b x h where b is Triangle Area of triangle 1 2 base height It is also possible to find the area of a triangle if the length of its sides is known by using Heron s formula As per the formula Area s s a s b s c s s a s b s c where s Perimeter 2 a b c 2 a b and c are the length of its sides
