Question

The area of a rectangular foot ball field is 24200 sq. m. Itis half as broad as it is long. What is the approxminimum distance a man will cover if he wishes to gofrom one corner to the opposite one?​

Answer 1

let length = a , breadth = b

according to ques a = b/2

a*b = 24200

a*a/2 = 24200

a^2 = 48400

a = 220 m

b = 110 m

distance Form one corner to another

d = √a^2 + b^2

d = √(220^2 + 110^2)

d = 110*√5

d = 245.96m

Hope it helped you
