Question

the length of a rectangular field is twice its breadth. If its area is 1800 square metre. Find the length breadth and perimeter of the field​

Answer 1

Answer:

Length = 60 m ; Breadth = 30 m ; Perimeter = 180 m

Step-by-step explanation:

Let the breadth be x m.

Then, length = 2x m

$Area = length*breadth$

but, area = 1800 m²

So, 2x × x = 1800

     2x² = 1800

     x² = 900

     x = √900

     x = 30

therefore, breadth = 30 m

and length = 30×2 = 60 m

perimeter = 2(30+60)

                 = 2×90

                 = 180 m
