Question

thee length of a rectangular Park is 3 times it's breadth if the perimetre of the park is 80 metre find it's dimensions
​

Answer 1

Step-by-step explanation:

let the breadth of park b= x

and length =3x

Perimeter of a rectangle=2*(l+b)

80=2*(3x+x)

80=6x+2x

80=8x

x=80/8

x= 10

therefore

breadth =10 m

and length=3*10

=30 m
