Question

length of a rectangular field is twice its breadth.tarun is running 2 times and covering a distance of 3km.find the length of the field

Answer 1

Distance covered = 3 km
Perimeter = 3 / 2 = 1.5 km

Let the breath be x then length will be 2x

Perimeter = 2( length + breath )
1.5 = 2( x + 2x)
1.5 / 2 = 3x
0.75 = 3x
0.75 / 3 = x
0.25 = x
Breath = 0.25 km = 250m
Length = 2(0.25)km = 0.5km = 500m
