Question

the length of the 2 sides of the paralleogram are 3x and 5x . the perimeter is 48o cm find the value of x

Answer 1

opposite sides of a parallelogram are equal
if 3x and 5x are the two sides that implies that other two sides are 3x and 5x itself
therfore perimeter of the parallelogram=3x+5x+3x+5x
we know that the perimeter given is 480 cm
therfore 3x+5x+3x+5x=480
16x=480
x=30

Answer 2

Answer:

x= 3

Step-by-step explanation:

We know parallelogram has equal sides so let the sides be  3x and 5x  

so, perimeter is 48

⇒2(3x + 5x)= 48

⇒8x = 24

⇒x = 3

and the sides are  3x= 9cm (put the value of x)

                               5x=15cm (put the value of x)

so, the sides are 9 cm,15 cm,
