let breadth = x,,,, length=2 x
perimeter =2( l+b)
60=2( l+b)
30=l+b
30=x+2x
3 x= 30
x= 10
length= 2x= 2(10)=20
breadth=x=10 m
area = l×b=20×10=200 m sq
hope it helps

Answer:224m2 is area
Step-by-step explanation:
Length=2+x
Breadth=x
Perimeter=2 (l+b)=60m
2 (2+x+x)=60
2 (2+2x)=60
2+2x=60÷2
2+2x=30
2x=30-2
2x=28
x=28÷2
X=14
Length = 2+14=16m
Breadth= 14m
Area= length×Breadth
= 16×14= 224m2
Hope it helps you..
