Answer:
perimeter = 2(l+b)=130
2(l+30)=130
2l+60=130
2l=130-60
2l=70
l=70/2
length=35m
area =l×b
area =35×30=1050m^2

Answer:
length = 35cm & Area = 1050cm
Step-by-step explanation:
Perimeter = 130cm
2( l+b ) = 130cm
2l + 2×30 = 130cm. [ b = 30cm ]
2l + 60 = 130cm
2l = (130-60)cm
l = 70cm /2
l = 35cm [Ans.]
Now,
Area = l×b
= (35×30)cm²
= 1050cm² [Ans.]
