Question

The area of a rectangular surface of a table is 6 m square and it is 3 cm long. find its perimeter

Answer 1

Answer:

40.6m

Step-by-step explanation:

A= 6m²

l= 3cm= 0.03m

     let the breadth be b.

A= l x b

6= 0.3 x b

b= 6/0.3

b=20 m

so,   P= 2 x (l + b)

         = 2 x (0.3 +20)

         = 2 x 20.3

         = 40.6m

Answer 2

Area of rectangle = lb = 6 m² = 60000 cm²

length = 3 cm

breadth = y

60000 =  y × 3

60000/3 = y

20000 = y

Perimeter of rectangle = 2(l+b)

Perimeter = 2(20000 + 3) = 20003 × 2 = 40006 cm

hope it helps !!
