Answer 1

Answer:

Varun Travel Greater distance and By - 60m more

Explanation:

Case 1 "Tarun":

Rectangular Field

|--> Length = 340m

|--> Breadth = 150m

Perimeter of Rectangle = 2 (l+b)

∴ P = 2*(340+150)

P = 2*(490)

P= 980

A.T.Q

3 rounds ==> 3 * 980 = 2940m ---(1)

Case 2: "Varun" :

Square field side = 250m

Perimeter Of Square = 4*Side = 4*250 = 1000m

A.T.Q

3 rounds ==> 3*1000 = 3000m ---(2)

Taking (1) and (2),

we get,

3000>2940

How much more = 3000 - 2940 = 60m

==> Varun Travel Greater distance and By - 60m more.

Answer 2

Answer:

I was not able to answer in your recent question so am answering it here

the side of the square path is 300m

$the \: perimeter \: = 300 \times 4$

$1200 \: m$

the cost of fencing is

$1200 \times 20$

$24000 \:$

the answer is Rs 24000
