Question

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? firnd tha perimeter of the park without track​

Answer 1

total lenght of path = 80 + 3 + 3 = 86 m

total width of path = 65 + 3 + 3 = 71 m

perimeter of path = 2(l + b)

                             = 2 (86 + 71)

                             = 314m

but there is 2 m left for door

so, total lenght of boundary having wall = 314 - 2 = 312 m

hope it helps :)

Answer 2

Answer:

Step-by-step explanation:

otal lenght of path = 80 + 3 + 3 = 86 m

total width of path = 65 + 3 + 3 = 71 m

perimeter of path = 2(l + b)

                            = 2 (86 + 71)

                            = 314m

but there are 2m left for a door

so, the total length of boundary having wall = 314 - 2 = 312 m

I hope this is helpful to you.
