Answer 2

Answer:22 cm and 28 cm

Given:

Length of rectangle is 16cm less than twice its breadth

Perimeter=100 cm

To find:

Its length and breadth

Solution:-

Let the breadth be x

Then length be 2x-16

We know that

Perimeter of Rectangle=2(l+b)

100=2(x-16+x)

100=2(3x-16)

100=6x-32

100+32=6x

132=6x

x=22 cm

--------

Then,

Breadth=22 cm

And length=2x-16

=2×22-16

=28 cm
