Answer:
Step-by-step explanation:
let the length be 2x and the breadth be x
So the formula for area of rectangle if length*breadth
14450m² = x * 2x
14450 = 2x²
x² = 14450/2
x² = 7225m²
x = √7225
x = ±85 m
Since the length can never be negative we tale it to be +85 m
So the length is 170 m and the breadth is 85m
