Question

The sides of a rectangular park are in the ratio 4:3. If its area is 2028 sq.m, Find the cost of fencing it at ru.3 per metre.​

Answer 1

4x 3x= 2028

12x×x= 2028

x^2=169

x=13

Answer 2

Answer:

Hlo mate

Step-by-step explanation:

Let, length=4x and breadth =3x

Area of rectangle =l*b

2028=4x * 3x

12x^2=2028

X^2=2028/12

=169

X=root 169=13

Length=4*13=52

Breadth =3*13=39

Now we need to find perimeter

2(l+b)

=2(52+39)

=2(91)=

=182m

Cost of fencing per meter=Rs. 3

=182*3

=546..
