Question

the area of rectangular field is 6000 m^2 . If the ratio of length and breadth is 3:2. find perimeter.​

Answer 1

Answer:-

Let the ratio be x

So, length = (3x)

breadth = (2x)

So, area = (length) × (breadth)

or, 6000 = (3x) × (2x)

or, x² = 1000

or, x = 10√10

So, length = 3 × (10√10) = 30√10 m

breath = 2 × (10√10) = 20√10 m

Hence, perimeter

= 2 × (length + breadth)

= {2 × (30√10 + 20√10)} m

= (2 × 50√10)m

= 100√10 m
