Question

The adjacent sides of a parallelogram are in the ratio 2:3 and its perimeter is 240 . The measure of sides will be

Answer 1

Answer:

Given that,

Adjacent sides =5:3

Perimeter =48cm

Length of each side=?

Opposite sides of parallelogram are equal,

Thus, 3rd and 4th side =5:3

Let length of sides be=x

Perimeter of parallelogram =sum of all sides

48=5x−3x+5x+3x

48=16x

x=

16

48

x=3cm

Length of 1 and 3rd side =15cm

Length of 2nd and 4th side 3×3=9cm

Length are =15cm.9cm,15cm,9cm

Answer 2

Step-by-step explanation:

Given: The two adjacent sides of the parallelogram is 2 and 3  

We have  

2x + 3x + 2x +3x = 240 [A parallelogram is a quadrilateral in which both pairs of opposite sides are parallel]

10x = 240 [Perimeter of a parallelogram is the total distance around the outside of the parallelogram]

X=240/10

  =24

Therefore ,

Sides 2x= 2(24) = 48

         3x= 3(24) = 72
