Question

The area f a rectangular field whose length is three times its breadth is 348 square meters. Find the perimeter of the field. Give answer correct upto 2 decimal place

Answer 1

let breadth be x m then length will be 3x
then 3x^2 = 348 => x^2 = 116
x = 10.77 then length = 3x = 32.31
then perimeter = 2(l+b) = 2(10.77+32.31)
perimeter = 2(43.08) = 86.16 m
