Question

After running 4 round of square field distance covered 16 km find length and area

Answer 1

Lenth=16/4

=4

Area= 4²

=16

Answer 2

let the length of a side of square field be a,

Given the length covered in 4 rounds of the field is = 16km.

i.e. 4*perimeter = 16 km.

perimeter = 16/4 km.

perimeter = 4 km.

Generally perimeter is the total length of the sides of a closed figure.

In this case perimeter is 4*length of side of square.

perimeter=4*a.

as perimeter in the above problem is 4 km.

then 4*a=4 km.

therefore length = 1 km.

Area of a square is A = side*side.

$area=side^{2}$

therefore A=4*4 sq.km.

$A=4^{2} =16 km^{2}$.

hope you understand. Any queries ask me.
