Answer:
Cross roads cover 0.96 hectares
Remaining area of park is 20.01 hectares
these are your answers ☝
Step-by-step explanation:
Area of park without cross roads = Area of ABCD - Area of EFGH - Area of IJKL + Area of PQRS
Area of ABCD = l*b=10*300=3000msq.
Area of EFGH=l*b=10*300=300msq.
Area of IJKL=l*b=700*10=7000msq.
Area of PQRS=l*b=s*s=10*10=100msq.
Area of park without cross roads =210000-3000-7000+100
=200100msq.
200100*1/10000hectares
=20.01 hectares
Area covered by roads = Area of IJKL+Area of EFGH-Area of PQRS
=7000+3000-100
=9900msq.
9900*1/10000hectares
=0.96 hectares
