The perimeter of a rectangle is 20 cm and its area is 24 cm square. Calculate the length and breadth of the rectangle.

Question

please help in the formation of question

Answer 1

Let width = x

Let length = y

 

Using the variables, create equations for perimeter and area.

 

2(x + y) = 20

 

   x + y = 10                  eq1      -----> perimeter

 

xy = 24                         eq2       ----> area

 

 

Simply find two numbers that multiply to 24 and add to 10.  No algebra is needed here.  Can you find those numbers?
