Question

ABCD is a parallelogram in which AB:BC= 2:1 . if the perimeter of ABCD is 36cm, find its length of its sides​

Answer 1

Step-by-step explanation:

ABCD is a parallelogram. now the opposite sides of a parallelogram are equal.

to find the perimeter = 2 (l+b)

length=1x

breadth=2x

2(1x+2x) = 2* 3x

2*3x= 36 cm

6x=36 cm

x= 36/6

length=6

breadth=6*2=12

Answer 2

perimeter of parallelogram = 2(l+b) = 36

let length is x and breadth is 2x

perimeter = 2(x+2x) = 36

x+2x = 18

3x = 18

x= 6

length = 6

and breadth is 2×6 = 12
