Question

Area of a blackboard is 5000 sq. cm. if its length is twice its breadth, find its
is length and breadth.​

Answer 1

Step-by-step explanation:

area =length×breath

let breath be X

5000= 2x×x

3x=5000

Answer 2

Answer:

area of blackboard =5000 sq.cm

let length be 2x

and breadth be x

we know ,

              area of rectangle = l * b

              5000 sq.cm = 2x * x

               5000 = 2x square

             5000/2 = x square

              2500 = x square

             root 2500 = x

                 50 = x

so,

length = 2x = 2*50 = 100

breadth = x = 50
