Question

6 Find the sides of a parallelogram whose perimeter is 40 cm, if one of its side is thrice of its adjacent side.​

Answer 1

Step-by-step explanation:

let one side be x, then adjacent side is 3x

now in parallelogram,

perimeter = 2(l+b)

40= 2(x+3x)

8x=40

x= 5cm

adjacent side=3×5= 15cm

all sides of parallelogram is 5,5,15,15
