Answer:
192 m²
Explanation:
The width of the playground is 8m.
Now it's length is three times more than its width.
thus its length is 8*3 = 24.
The area thus is 24*8 = 192 m²
If it were as long as it is wide, the area would be that of an 8-meter square:
(8 m)² = 64 m²
It is 3 times as long, so the area is 3 times that value:
3 × 64 m² = 192 m²
