Question

a path 3m wide runs along inside of rectangle park of length 90 m and breadth 10m. find the area of the path

Answer 1

area of rectangle is =length×breath

so,area will be>90×10=900meter square

new length=90+3=93m

new breath=10+3=13 m

area will be=length×breath

so,. =93×13=1029m square

so the area of path will be=(area of outer rectang-- area of inner rectangle)

= (1029-900)

=129 meter square
