Answer 1

ANSWERS

1. area of square field=119025 sq m.

one side= sqrt of 119025= 345 meters

perimeter=4a= 4*345 =1380 meters

if the man took two rounds of

park then distance covered= 2*1380=2760 meters

2. let length of diagonal be x.

According to question,

(22)²+(120)²=x²

= 484+14400=x²

= 14884=x²

=122=x

=x=122 cm

3. area of sq field=164025 m²

fencing rate= Rs 15/m

total cost= 164025*15= Rs 2460375
