Answer
let the breadth be x
then, the length= 2x
area of rectangular field= length x breadth= 2450m²
therefore,
2x*x= 2450
= 2x²= 2450
= x² = 1225
= x = √1225
= x = 35m
therefore, length = 2x = 2 x 35 = 70m
now, perimeter of rectangular field = 2( l + b)
= 2( 70 + 35)
= 2(105)
=2 x 105
= 210
therefore, perimeter= 210m

Answer:
L = 2B
Area = 2450
Step-by-step explanation:
L × B = 2450
2B × B = 2450
2B² = 2450
B² = 2450 / 2
B ² = 1225
B = √1225
B = 35
L= 35 × 2
= 70
PERIMETER
2L + 2B
2× 70 + 2 × 35
140 + 70
210 m
