John le Jack ba na le metsotso e le 30 ya go tsamaya go ya sekolong mmogo.  Ba tsaya metsotso e le 6 go fitlha kwa sekhutlong kwa laeborari e leng teng. Ba tsaya metsotso e mengwe e le 13 go fitlha kwa seteishaneng sa ba pompi ya molelo. Ba saletswe ke metsotso e mekae go fitlha kwa sekolong ntle le go fitlha thari?

Shania is designing her own dress, and decides to make it a longer dress by extending the dress by 50% of its original length. She also adds 20cm to the bottom of the dress with a lace trim. If the final design is 140cm long then how long, in centimeters, was the dress in its original design?
John le Jack ba goroga kwa laeborari ba saletswe ke metsotso e le 30 - 6 = <<30-6=24>>24 go fitlha kwa seteishaneng sa ba pompi ya molelo.
Morago ga foo ba goroga kwa seteishaneng sa ba pompi ya molelo ba saletswe ke metsotso e le 24 - 13 = <<24-13=11>>11 go fitlha kwa sekolong ntle le go fitlha thari.

Without the lace trim, the dress is 140cm full length – 20cm lace trim = <<140-20=120>>120cm.
Let's assume the dress was originally x cm in length.
Half the original length is x/2.
Adding the original length and the extended length, which is x+x/2 = 120
3/2x = 120
The orginal length is x= 80 cm
