Find the perimeter....

Answer»

ANSWER:

540m

Step-by-step explanation:

GIVEN ratio of LENGTH :breadth is 5:4

Let the length be 5x and breadth be 4x given area is 18000 IMPLIES

Length ×breadth =18000

(5x)×(4x)=18000

20x^2 =18000

X^2 =900 IMPLIES

X=30

LENGTH =5x=5×30=150

Breadth =4x=4×30=120

Perimeter =2(length +breadth)

Perimeter =2(150+120)

Perimeter =2×270

Perimeter =540m
