Please answer me soon

Answer 1

The cost of paving the path is 5100 Rs and the cost of covering the remaining part is 9424 Rs.

Step-by-step explanation:

Let the external boundaries of the plot be =  PQRS

Internal boundaries be = ABCD

Length QR = 35 m

Breadth RS = 20 m

• Area of PQRS = QR x RS = 35 X 20 = 700 m^2

Length CD = 35 -2 -2 = 31 m

Length DB = 20 -2 2- = 16 m

• Area of ABCD = 31 m x 16 m = 496 m^2

• Area of path = 700 m^2 - 496 m^2 = 204 m^2

Now the cost = 204 m^2 x 25 = 5100 Rs

Now cost of covering the remaining part = 496 x 19 = 9424 Rs
