The length of a rectangular park is two times the breadth of the park. The perimeter of the park is
180 cm. Find the length and the breadth of the park​

Answer 1

let the breath be x

length = 2x

perimeter = 180

perimeter of rectangle = 2 ( l + b )

180 = 2 ( 2x + x )

180 = 4x + 2x

180 = 6x

$x = \large\bold{\frac{180}{6}}$

x = 30 ( breath )

2x = 60 ( length )

$\large\mathbb{ANSWER}$
