l=2b
area of rectangle=2450
lb=2450
2b^2=2450
b^2=2450/2
b =√1225
b=35
mdragibuddin:
then length 2×35= 70m perimeter= 2(l+b) = 2(35+70)= 2× 105 = 210m answer is right
Thank you for correcting my mistake

2b*b= 2450m²
2b²=2450/2
b²= 1225
b=√1225
breadth=35
length=2*35=70
hope this solve your problem
