Question

The perimeter of a rectangle piece of paper is 13 cm.If its width is 2:5 cm.then find its length(in cm)?

Answer 1

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 = 2x(length+breadth)

Perimeter 2xlength +

2xbreadth

Putting the given values we get,

13=2×1+ 2x2.5

13= 21+5

13-5=21.

8=21

1=8/2

1=4cm

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