Question

A wall clock is shape in a regular hexagon 25 cm on each side. Find its perimeter in decimeter

Answer 1

Length of hexagon of each side = 25cm
number of sides a hexagon has = 6
So perimeter of hexagon. = 25 x 6
= 150 cm

Metric measurements of length

Kilometer = 10^3 ( 1000 km )
Hectometre = 10^2 ( 100 hm )
decameter. = 10^ 1 ( 10 dm )
standard unit(metre) = 10^0 ( 1 m )
decimetre = 10^-1 ( 1/10 dm )
centimetre. = 10^-2( 1/100 cm )
millimeter. = 10^-3( 1/1000mm)

hence to calculate 150 cm we will divide it by 10

=> 150/10
=> 15 dm ( decimetre )

So our evaluation in cm to decimetre of 150 is 15 ( decimetre )

hope this helos you
