Question

a rectangular grassy plot is 75 M long and 45 M broad it has a path of width to metre all around it on the inside find the area of the path and the cost of constructing it at 175 rupees per metre square

Answer 1

lenth of field = 75 m

breadth of field = 45 m

length of field left after path construction = 75 - 2*2= 71 m

breadth of field left after path construction = 45 - 2*2= 41 m

total area of path = area of total field - area of field left after path construction

= 75*45 - 71×41 = 464 m^2

total cost of construction = path area * cost per m^2

= 464*175= 79808 rs

Answer 2

Answer:

75-2*2=71m

45-2*2=41

Step-by-step explanation:

75*45- 71*41=464m. 464*175=81200
