Question

the breadth of rectangle feild is 3/7 times of it's lenght find the ditermination of ractangular field if the perimeter is 140m​

Answer 1

Answer:

let the length of the rectangular field be x m

breadth =3/7x

ATQ, 2(x+3/7x) =140

or, 2(7x+3x/7) =140

or, 10x/7=140/2

or, 10x/7=70

or, x=70×7/10

or, x=49 m

Length=49 m

breadth = 3/7×49 =21 m

so, length=49 m and breadth = 21 m
