1.	The perimeter of a rectangle piece of paper is 13 cm. If its width is 2.5 cm. Then find its length (in cm) please answer fast and it should be correct explain also because I have to write on my own just want to see how to do it.
Answer» Answer: Length=4cm. Step-by-step explanation: Perimeter of the rectangular paper= 13cm Width of the paper(b)= 2.5cm Length of the paper=? So we KNOW that, Perimeter = 2×(length+breadth) Perimeter=2×length + 2×breadth Putting the given values we get, 13=2×l+ 2×2.5 13= 2l+5 13-5=2l. (NOTE: l= length) 8=2l l=8/2 l=4cm So, the VALUE of length is 4cm... Thank you.. Hope it HELPS..

Answer:

Length=4cm.

Step-by-step explanation:

Perimeter of the rectangular paper= 13cm

Width of the paper(b)= 2.5cm

Length of the paper=?

So we KNOW that, Perimeter = 2×(length+breadth)

Perimeter=2×length + 2×breadth

Putting the given values we get,

13=2×l+ 2×2.5

13= 2l+5

13-5=2l. (NOTE: l= length)

8=2l

l=8/2

l=4cm

So, the VALUE of length is 4cm...

Thank you..
