Question

Find the dimension of the rectangular field whose length and breath are in the ratio 6:4 and whose area is 21600 meter square

Answer 1

Let the meet of dimensions be x.

Since Area = l*b

= 6x * 4x = 21600 m^2

= 24x^2 = 21600 m^2

= x^2 =21600/24

= x^2 = 900m^2

= x = 30m.

Hence dimensions are 6*30m and 4*30m.

= 180m and 120m.

Hope it's helpful to u.

Answer 2

let the length is 6x
and breath is 4x
given, area= 21600m sq.
area = 6x*4x
= 24x^2then


24x^2= 21600
x^2=21600/24
x^2=900m sq.
then
x= 30 m
hence the length is 6*30=180m
breath=4*30=> 120m
