Question

A rectangular field which is twice as long as it
is broad, has an area of 14450 sq m. What is
Its perimeter?
(A) 85 m
(B) 510 m
(C) 165 m
(D) 170 m​

Answer 1

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
