Breath of the rectangle play ground is 8m...let us take it has x
length is 3 times as long as breath...let us take it as y
then y=3x
y=3(8) since x=8
area of rectangle is product of its length and breath
it is 8×24
area of rectangle is 192
0 0 0
length is 3times of breadth
then length=8×3=24m

given that that play ground is in rectangular shape.
therefore area of rectangle=2 (l+b)

area=2 (24+8)
=2 (32)
