Let us consider a square as a rectangular object whose length is of a unit and breadth is of a unit. To find the area of a rectangle multiply the length by the width. Where A Area of the square l Length of the object b Breadth of the object.
A 4pr 2 sphere where r is the radius of the sphere.
Since each side of a square is the same it can simply be the length of one side squared. In the above example the area of the collage comes out to be 40 and the unit of area is square centimeter. Solid Geometry is concerned in calculating the length perimeter area and volume of various geometric figures and shapes. Study the formula below carefully before looking at the examples.
