Question

CE
11. A park 80 m by 65 m has a 3 m wide track
all around it. A wall has been constructed
around the track leaving a space for gate
which is 2 m. What is the length of the
outer boundary leaving the gate which
has a wall? Find the perimeter of the park
without track.​

Answer 1

Step-by-step explanation:

Length of outer boundary leaving the gate =(3+65+3)+(3+80+3)+(3+65+3)+(3+80−2+3)

=71+86+71+84

=312m

Perimeter of park =2×(65+80)

=290m
