Question

A rectangular field which is twice as long as it is broad has an area 14450 sq m. What is its perimeter?​

Answer 1

Answer

Let X = the breadth of the field in meters

Then the length is 2X

The area is the product of the breadth and length X(2X) = 2(X**2) = 14450

14450 / 2 = 7225

X = square root (7225) = 85

2X =170

The perimeter (distance around) is 2(X + 2X) = 6X

The perimeter is 510 meters.
