Question

the perimeter of triangle is 57 cm, find me eng
Length of a rectangle is 16 cm less than twice its breadth. I the perimeter of the
rectangle is 100 cm, find its length and breadth​

Answer 1

Answer:

length=28cm

breadth=22cm

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

      6x=132

      x=22cm

Then length is  

      =2x−16

       =44−16=28 cm.

Therefore length=28cm and breadth=22cm
