Fa diterena tse pedi di tswa mo seteishaneng di ya kwa dikgatlong tse di farologaneng, mme terena e nngwe e tsamaya ka dikilometara di le 97 ka ura fa e nngwe e tsamaya sephatlo sa sekgala seo ka ura, di tla bo di le bokgale bo bo kana kang go tswa mongwe go ya go yo mongwe morago ga diura di le 3?

Tony is painting a room with four walls. The north and south walls are 10 x 8 feet. The east and west walls are 5 x 8 feet. A gallon of paint can cover 20 square feet and cost $12. How much will it cost to paint the room?
Ereka terena e nngwe e tsamaya sephatlo sa lobelo lwa terena e e tsamayang ka dikilometara di le 97 ka ura, seo se raya gore terena eo e tsamaya ka dikilometara di le 97/2= <<97/2=48.5>>48.5 ka ura.
Ka jalo, go bona sekgala se se tsamaiwang ka ura nngwe le nngwe ka kakaretso re tlhakanya lobelo lwa diterena ka bobedi go nna kakaretso ya 97+48.5=<<90=145.5>>145.5 dikilometara tse di tsamaiwang ka ura nngwe le nngwe.
Seno se raya gore mo diureng di le 3 di tla bo di tsamaile dikilometara di le 145.5*3= <<145.5*3=436.5>>436.5 go tswa mongwe go ya go yo mongwe. 
#### 436.5 

The north and south walls are 80 square feet each because 10 x 8 = <<10*8=80>>80
The east and west walls are 40 square feet because 5 x 8 = <<5*8=40>>40
The south and north walls total 160 square feet because 80 x 2 = <<80*2=160>>160
The East and west walls total 80 square feet because 40 x 2 = <<40*2=80>>80
All the walls total 240 square feet because 160 + 80 = <<160+80=240>>240
He will need 12 gallons of paint because 240 / 20 = <<240/20=12>>12
It will cost $144 because 12 x 12 = <<12*12=144>>144
#### 144
