Question

5. The length and breadth of a rectangular plot are 80 m and 50 m
respectively. A road of width 5 m is prepared in the inner side of
the plot. Find the perimeter of the inner rectangular plot.
​

Answer 1

Step-by-step explanation:

given that l=80m and b=50m ,

when a road of width 5 is constructed then new length = l-10 and breadth =b-10

perimeter =2(l+b)

2×(110)=220m
