Answer:
Firstly, find the area of full page by using length \[\times \] breadth. Also, find area of half page and to get required cost, we multiply the area of half page by rate of advertising i.e., \[Rs.\frac{300}{10}\] [\[\because \] rate = Rs. 300 per 10 sq. m] Given, length of each page of the magazine = 24 cm and breadth of each page of the magazine = 15 cm \[\therefore \] Area of the full page of the magazine \[=Length\times Breadth\] \[=24\text{ }cm\times 15\text{ }cm\] \[=360\text{ }sq\text{ }cm\] \[\because \] Company decided to order the half page of advertisement. \[\therefore \] Area of half page of the magazine \[=\frac{360}{2}\] \[=180\,sq\,\,cm\] Given, cost of per 10 sq. m = Rs. 300 Cost of 1 sq. m \[=Rs.\frac{300}{10}\] Cost of 180 sq. m \[=\frac{300}{10}\times 180\] \[=300\times 18\] \[=Rs.\,\,5400\] Hence, the company will pay Rs. 5400 for it.
