Each side of a regular polygon is 4.05 cm in length. How many sides does the polygon have if its perimeter is 0.486m ?
Rama weights 45kg. Meena is 1.09 times of Rama's weight and seema is 0.95 times of meena's weight . Find the total weight of 3 gilrs

posting a second time will not speed things up if no one happens to be looking...
For the perimeter, you surely know that it is the sum of the sides. So, if the are n sides, you have
4.05n = 486
the weights add up to
45(1 + 1.09 + 0.95) = ?
To find out the number of sides of the polygon, we can divide the perimeter of the polygon by the length of one side.
To calculate the perimeter of the polygon in meters, we need to convert the length of one side from centimeters to meters. Since there are 100 centimeters in one meter, we divide the length of one side by 100.
Length of one side in meters = 4.05 cm / 100 = 0.0405 m
Now, we can calculate the number of sides by dividing the perimeter of the polygon by the length of one side.
Number of sides = Perimeter of the polygon / Length of one side
Number of sides = 0.486 m / 0.0405 m
Number of sides ≈ 12
Therefore, the polygon has approximately 12 sides.
