Question

Q6. The area of a rectangle is 100cm 2 . If its breadth is 5cm, find its length.

Answer 1

Length of a rectangle is 16 cm less than twice its breadth. If the perimeter of the rectangle is 100 cm, find its length and breadth.

Step-by-step explanation:

Let breadth of the rectangle is x.

Then its length will be 2x−16.

According to the problem,

2(length+breadth)=100

2(x+2x−16)=100

or, 6x=132

or, x=22.

Then length is

=2x−16

=44−16=28 cm.
