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 = 30m

BREADTH = 60m

PERIMETER = 180m

Step-by-step explanation:

breadth - x

length - 2x

area - 1800m^2

given: x*2x= 1800

2x^2=1800

x^2= 1800/2

     = 900

x = √900

 = 30

LENGTH = 30m

BREADTH = 2x

                 =  2*30

                 = 60m

PERIMETER = 2(l+b)

                    = 2(30+60)

                   = 2*90

                   = 180 m
