Question

in figure a path 2.5 m wide runs along inside the boundary of a square field whose each side is 65 m the path is to be covered with the red gravel and the rest of the field to be manured. find the total expenses involved. if the cost of covering the path with red gravel is rs 1.50 per m sq and that of menuring the field rs 0.50 per m sq​

Answer 1

Step-by-step explanation:

area of the whole square =(65 x 65)= 4225meter square

side of the inner square (65+4(2.5))=55

area of the inner square =(55 x 55)=3025 meter square

∴area of the path=(area of whole square - area of inner square)

=(4225-3025)

=1200meter square

cost of gravelling=(1200 x 1.50)= 1800

cost of manuring the field=(3025 x 0.50)=1512.5
