Question

After running 4 rounds to a square field , a distance covered is 16km . Find the length and area of ground

Answer 1

Distance in 4 rounds = 16km

so distance in 1 round= 16/4 = 4 km

now since distance of 1 round = perimeter of square.

so perimeter = 4 km

perimeter = 4* side of square

4 = 4*side of square

side of square = 4/4 = 1 km

now area of square= side²

= 1² = 1 km²

so length of the field = 4 kms

and area of the field = 1 km²
