Question

Perimeter of a rectangle is 48cm and length is two times of breadth. Find length and breadth of rectangle

Answer 1

Answer:

let breadth =x and length =2x

so perimeter = 2 (l+b)

=2(2x+x)

2(3x)=6x

6x=48. x=8

breadth is 8 cm and length is 16 cm

Answer 2

Let, the breadth of rectangle be 'x' cm

so, length of rectangle will be 2x

perimeter of rectangle = 48 cm

We know,

perimeter of rectangle = 2( l + b )

48 = 2( 2x + x )

48 = 6x

x = 8

Answer :

the breadth of the rectangle = x = 8 cm

the length of the rectangle =2x = 16 cm
