Question

The area of a square plot is 25281 sq m. Find the cost of fencing the plot at the rate of rupees 75 per metre

Answer 1

Answer:

a^2=25281

a=159m

cost= 4×159×.75

=477 rupees

Answer 2

Step-by-step explanation:

given :

The area of a square plot is 25281

let each side of the plot be 'a'

so A.T.Q

a²=25281 (area of square = side × side )

so

$a = \sqrt{25281}$

so a=159m because,

$\sqrt{25281} = 159$

so for fencing we have to find the perimeter of the plot

which is equal to 4 × a=4×159=636m

so the cost of fencing @ of 75 ruppe :-

75×636

=>47700 rupees
