<prompt> Fumana polelo ea lipalo e balang sebaka sa khutlotharo.nan  <response>: Instruction in English: Derive a mathematical expression that calculates the area of triangle. . Response in English: To derive a mathematical expression for calculating the area of a triangle, we need to consider the three sides of the triangle and their respective lengths, denoted as a, b, and c. We can use Herons formula, which states that the area of a triangle can be calculated using the lengths of its sides as follows:1. First, we compute the semi-perimeter of the triangle, which is given by the formula: s a b c 22. Next, we can calculate the area of the triangle using the formula: Area sqrts s - a s - b s - cSo, the area of a triangle with side lengths a, b, and c is given by the mathematical expression: sqrts s - a s - b s - c, where s is the semi-perimeter of the triangle. . Response in Sesotho: Ho fumana polelo ea lipalo bakeng sa ho bala sebaka sa khutlotharo, re lokela ho nahana ka mahlakore a mararo a khutlo-tharo le bolelele ba ona ka ho latellana, a tšoailoeng e le a, b, le c. Re ka sebelisa mokhoa oa Heron, o bolelang hore sebaka sa khutlo-tharo se ka baloa ho sebelisoa bolelele ba mahlakoreng a sona ka tsela e latelang: 1. Ntlha ea pele, re bala semi-perimeter ea triangle, e fanoeng ke foromo: s a b c 2 2. Ka mora moo, re ka bala sebaka sa kgutlotharo ka ho sebedisa foromo: Sebaka sqrts s - a s - b s - c Kahoo, sebaka sa kgutlotharo se nang le bolelele ba mahlakore a, b, le c se fanoe ke polelo ya dipalo: sqrts s - a s - b s - c, moo s e leng semi- pherimithara ya kgutlotharo.
