Question

A rectangular field which is twice as long as it is breadth, has an area of 14450 m.what is the perimeter?​

Answer 1

Step-by-step explanation:

If the field is twice as long as it is wide, we can find the shorter side length by taking the square root of half the area; sqrt(14450/2)=85. The field is 85 meters wide and twice as long, therefore the perimeter is twice the width plus twice the length, or 85*2 + (2*85)*2 which is 510 meters.
