​

Answer 1

Answer:

5536sq.m

Step-by-step explanation:

a.  length= 400m,     b.     breadth= 300m      there is an area of walking track 4m wide built around.                           c.  so, inner length= 400-(4+4)=392m              d. inner breadth= 300-(4+4)= 292m                                                                                                e. area oleft for a children for playing= (400times\300)-(392\times292)                                                                           f area left for children for playing= 5536                                                                      g. hence an area left for children for playing is 5536
