Question

The sides of a rectangle plot are in
the ratio 3:2 and its area is 6 hectares.
Find its perimeter.​

Answer 1

sum of the ratio = 3+2 =5

therefore, length of the rectangular plot = 3/5*6hectares

3/5*60000m (1hectare=10000m )

3*12000=36000m

breadth of the rectangular plot=

2/5*60000

2*12000=24000m

perimeter = 2(L+B)

=2(36000+12000)

=2*48000=96000m

1m =1/10000hectares

96000m= 96000/10000=9.6hectares

Answer 2

Answer:

let the length be 3x and the breadth be 2x

area of rectangle = L×B

6 = (3x)(2x)

6 = 6x^2

6÷6 = x^2

1 = x^2

√1 = x

1 = x

breadth = 2x length = 3x

=2×1 = 3×1

=2 = 3

perimeter of rectangle = 2(L+B)

= 2(3+2)

= 2(5)

= 10
