Question

Find the perimeter....

Answer 1

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

Answer 2

SOLUTION ☺️

Given,

Area of a rectangular field= 18000m^2

The ratio of length and breadth= 5:4

So,

let the Ratio be x

Length= 5x

Breadth=4x

=) l× b= 18000m^2

=) 5x× 4x= 18000m^2

=) 20x^2 = 18000m^2

=) x^2= 900m^2

=) x= √900m

=) x= 30m

Length = 5x= 5× 30= 150m

Breadth= 4x= 4×30= 120m

Now,

Perimeter

=) 2(150+ 120)

=) 2(270) m

=) 540 m
