Answer 2

Answer:

Perimeter = 86m

Step-by-step explanation:

Given that Area of Rectangular Park = 460m^2

let's length = x , breadth = y say

Given that,the length is 15%more than its breadth

=> x = ( 115 )y / 100

=> x = ( 23y )/20

therefore , x = 23y/20

Area = l*b = 460

=> xy = 460

=> ( 23y/20 )y = 460

=> y^2/20 = 20

=> y^2 = 400

=> y = √400

=> y = 20

and x = 23(20)/20 = 23

therefore, length(x) = 23m , breadth(b) = 20m

Now we need to find perimeter of Park

Perimeter = 2( x + y )

= 2( 23 + 20 )

= 2(43)

= 86m

therefore, Perimeter of Park = 86m
