Question

EXERCISE 15.2
long its border. Find the area of the path.
rectangular field is 100 m long and 80 m wide. A path 10 m wide path is to be built inside the field all
along its border find the area of the path​

Answer 1

Answer:

Answer:area of path =area of outer field -area of inner field

Answer:area of path =area of outer field -area of inner field=8000-4800

Answer:area of path =area of outer field -area of inner field=8000-4800=3200m2

dimensions of outer field

l=100m

b=80m

area of outer field= 100*80

=8000m2

dimensions of inner field

l=100-2*10

=100-20

=80m

b=80-2*10

=80-20

=60m

area of inner field=80*60

=4800m2

area of path =area of outer field -area of inner field

area of path =area of outer field -area of inner field=8000-4800

area of path =area of outer field -area of inner field=8000-4800=3200m2
