Question

one side of a parallelogram is 2.5 times it's consecutive adjacent side if the perimeter of the parallelogram is 70m,find it's area and the measure of all it's sides​

Answer 1

Answer:

Work input is work done on a machine to get the desired output. Work output is the amount of desired work that is done by a machine.

Answer 2

Correct answer:-

Let ABCD is a parallelogram

Let AB=x m

Adjacent side BC=(x+2.5) m

Now,

CD=AB=x m [Opposite sides of parallelogram are equal]

And AD=BC=(x+2.5) m [Opposite sides of parallelogram are equal]

Perimeter =AB+BC+CD+AD

⇒51=x+x+2.5+x+x+2.5

⇒51=4x+5

⇒4x=51−5

⇒4x=46

⇒x= 46/4

⇒x=11.5 m

So,

AB=CD=11.5 m

and BC=AD=11.5+2.5=14 m [Ans].

hope it helps ♡
