Answer» here is a similar question- Area of the rectangle =Length×Breadth=65×50=3250m2Length×Breadth=65×50=3250m2 Given Width of the Path = 2m Length of the Path is Parellel to the side , Hence Length = 65 m Area of the Path 1 =Length×Width=65×2=130m2Length×Width=65×2=130m2 Given Breadth of the Path = 2m Length of the Path2 is Parellel to the other side , Hence Length = 50 m Area of the Path2 =Length×Breadth=50×2=100m2Length×Breadth=50×2=100m2 Add Both the Area of the Path =130+100=230m2130+100=230m2 Area of the Common Field ABCD =2×2=4m22×2=4m2 As both path are overlapping each other, so to calculate the area of shaded portion area of one square should be deducted from the area of the total path. ∴∴Total Area for the Path Construction =230−4=226m2230−4=226m2 ∴∴Cost of Constructing the Path =230−4=226×69=15594 |
