Answer by sudhanshu_kmr(1152) (Show Source): You can put this solution on YOUR website!
Area of walk = (30+4)*(10+4) - 3010
= 3414 - 300
= 476 - 300
= 176
so, 176 square meters.
Height of parallelogram = 3sqrt(2)
area = base * height = 3sqrt(2) * 10 sqrt(3)
= 30sqrt(6)
= 73.484 square units
Circumference = 2* pi*r
= 31.428
