Answer 1

Answer:

first we need to find the are of tarring road and then we have to multiply with rate of tarring per square km

Step-by-step explanation:

lenght =25km

breadth= 750m=750/1000=0.75km

area of tarring road= lxb

                                   25km x 0.75km

                                   18.75 sq km

cost of tarring per km= 5.25 rupee

cost of tarring road 18.75sq km =18.75 x 5.25

                                                       98.4975rupees
