Question

Area of a square filed is 105625 m2. A man cycles along its boundary at 18km/hr. How long will it take him to reach the starting point.

Answer 1

area of Square field = 1,05,625m

km/h = 18

Area =X

let, find the square root of √ 105625

√105625= 325

let we know that , DISTANCE/ TIME

5

18*** /

18

5 m/s

Area of Square = 4*4

so, 325** 4= 1,300

X=1300/5

=260second

= 4 minutes 20 second
