Hapa kuna suluhisho la swali la 2(b):

Ili kupata gharama ya kupaka rangi bodi, tunatumia eneo la bodi tulilolipata katika swali la 2(a) na gharama ya kupaka rangi kwa kila mita ya mraba.

  1. Tambua eneo la bodi.

    Kutoka swali la 2(a), eneo la bodi ya matangazo ni 71 m271 \text{ m}^2.

  2. Tambua gharama ya kupaka rangi kwa kila mita ya mraba.

    Gharama ya kupaka rangi ni Ksh 250 kwa kila mita ya mraba.

  3. Hesabu gharama yote ya kupaka rangi.

    Gharama yote = Eneo la bodi ×\times Gharama kwa kila mita ya mraba.

    Gharama yote=71 m2×Ksh 250/m2\text{Gharama yote} = 71 \text{ m}^2 \times \text{Ksh } 250/\text{m}^2 Gharama yote=Ksh 17750\text{Gharama yote} = \text{Ksh } 17750

    Gharama ya kupaka rangi bodi ni Ksh 17750\text{Ksh 17750}.
