rope is 200 meters long.
1 centimeter = 1 meter divided by 100 = .01 * meter
12 centimeters * .01 = .12 meters.
-----
rope is divided into 2 parts.
1 part is .12 meters longer than the other part.
the sum of the 2 parts is equal to 200 meters.
-----
let x = length of one part.
let x + .12 = length of the other part.
-----
x + x + .12 = 200
2x + .12 = 200
subtract .12 from both sides of the equation to get
2x = 200 - .12 = 199.88
divide both sides of equation by 2 to get:
x = 199.88 / 2 = 99.94 meters.
-----
1 part is equal to x which is equal to 99.94 meters.
the other part is equal to x + .12 = 99.94 + .12 = 100.06
-----
100.06 + 99.94 = 200 meters
-----
your answer is:
the shorter part is 99.94 meters long
the longer part is 100.06 meters long.
