Question

please solve q.no.1 with full sollution
​

Answer 1

Answer:

length = 9x

breadth= 5x

area of rectangle= l× b

14580=9x×5x

14580=45x^2

√14580= 45x

20.74=45x

x=20.74/45

x= 2.68

the cost of surrounding field is 2.68×Rs.3.25

=8.71

Answer 2

Answer:

cost of fencing = ₹1638

Step-by-step explanation:

$\implies$$Let\:Length=9x;breadth=5x$

$\implies$$Area=length×breadth$

$\implies$ $14580=9x×5x$

$\implies$ $\Large\frac{14580}{45}=x^{2}$

$\implies$ $x=\sqrt{324}$

$\implies$ $x=18$

Now substitute x value in length and breadth :

length = 9x = 9(18) = 162m

breadth = 5x = 5(18) = 90m

$\implies$ $Perimeter=2(l+b)$

$\implies$ $P=2(162+90)$

$\implies$ $P=2(252)$

$\implies$ $\boxed{perimeter=504m}$

For 3.25 for 1 m

then ₹x for 504 m

$\implies$ $Cost\:of\:fencing=504×3.25$

$\implies$ $\boxed{\boxed{cost\:of\: fencing=1638}}$
