Question

a rectangular plot, 36m long and 28m broad, has two concrete roads 5m wide running in the middle of the park, one parallel to the length and the other parallel to the breadth. What would be the total cost of gravelling the plot, excluding the area coveredby the roads, @ rs. 3.60 per sq m?

Answer 1

$area \: of \: rectangle = length \times breath \\ given \: length = 36m \: and \: breadth = 28m \\ area \: of \: rectangle \: = 36m \times 28m \\ = 1008 {m}^{2}$
