<prompt> Bala sebaka sa khutlotharo e lekanang le bolelele ba 15 cm.nan  <response>: Instruction in English: Calculate the area of an equilateral triangle with side length 15 cm. . Response in English: The formula for calculating the area of an equilateral triangle is A sqrt3 4 a2, where a is the length of a side of the triangle. In this case, the length of each side of the equilateral triangle is 15 cm, so we can plug this value into the formula to get:A sqrt3 4 152 A 97.43 cm2So, the area of an equilateral triangle with side length 15 cm is approximately 97.43 cm2. . Response in Sesotho: Mokhoa oa ho bala sebaka sa khutlotharo e lekanang ke A sqrt3 4 a2, moo a e leng bolelele ba lehlakore la khutlotharo. Tabeng ena, bolelele ba lehlakore le leng le le leng la kgutlotharo e lekanang ke 15 cm, kahoo re ka kenya boleng bona foromong ho fumana: A sqrt3 4 152 A 97.43 cm2 Kahoo, sebaka sa khutlotharo e lekanang le bolelele ba 15 cm e ka ba 97.43 cm2.
