Let the side of an equilateral triangle be m. Show the perimeter of the triangle with the help of m.
Perimeter = sum of three sides
Let the side of a regular hexagon be denoted by m. Show the perimeter of the hexagon with the help of m.
(All sides are equal in regular hexagon)
Side of regular hexagon = m
Perimeter = sum of all sides
In the given figure a cube, 3 – D cube is shown. It has six identical squares as all the sides are equal so same six faces. Let the length of a side of cube be given by m. Find formula for total length of the cube.
Length of an edge = m
Number of edges = 12
Total length of the edges = total number of edges × Length of each edge
Diameter of a circle is a line which passes through the centre and joins two points of circle. (In the given figure XY is a diameter of circle; c is centre.) Express the diameter of the circle (d) in form of its radius(r).
d = twice the radius
