Question

the length of rectangular field is twice its breadth if the perimeter of the field is 150 metres find the length and breadthbe

Answer 1

let its breadth be x
then the length be 2x
therefore,
2×(x+2x)=150
or,6x=150
or,x=25
therefore the breadth be 25m and length be 50m

Answer 2

breadth=x

length=2x

p = 150

p = 2(l×b)

150 = 2 (2x×x )

150 = 2(3x)

150 = 6X

X = 150÷6

X= 25

BREADTH= X

              = 25

LENGTH= 2X

              2 ×25

             = 50
