Answers
Answer:
first you have to find the area of playground is equal to 120 into 80 m= 9600 metre then you have to add in all six because the track is 3 metre wide so in a both side we well add we get 126 in 86 metre is equal to10836 metre square the area of playground from the area of rectangle then we will get 1236 it is the area of walking track if my answer is correct please market brainless answer
Length of the rectangular playground = 120m
Breadth = 80m
Area of the playground along the track
= 120m × 80m
= 9600 m²
Area of the playground without the track
Length = 120m - 3m+3m
= 120m - 6m
= 114m
Breadth = 80m - 3m + 3m
= 80m - 6m
= 74m
Area = 114m × 74m
= 8436 m²
Area of the walking track = 9600 - 8436
= 1164 m²
☆ Thus, the area of the walking track is 1164 m²
