Answer 1

Answer:

Step-by-step explanation:

An area left for children for playing is 5536 sq.m.

Step-by-step explanation:

Outer length = 400 m

Outer breadth = 300 m

There is an area of walking track 4m wide built all around

So, Inner length = 400-(4+4)=392 m

Inner breadth = 300-(4+4)=292 m

Area left for children for playing = Outer area - inner area

Area left for children for playing =(400 \times 300)-(392 \times 292)

Area left for children for playing =5536 sq.m.

Hence an area left for children for playing is 5536 sq.m.
