Answer:
200m²
Step-by-step explanation:
Area of playground be = x m²
12% of playground in meters = 12/100×x
= 12x/100
60% of playground in meters = 60/100×x
= 60x/100
Remaining area = 56m²
Total area = Bad area of playground + grassy area of playground + remaining area of playground
=> x = 12x/100 + 60x/100 + 56
=> x = 72x/100 + 56
=> x - 72x/100 = 56
=>(100x-72x)/100 = 56
=> 28x/100 = 56
=>28x = 5600
=>x =5600/28
=>x = 200m²
