Question

solve the math question the side of a rectangular Park are in ratio 4 : 3.If its area is 2028 sq. m.Find the cost of fencing it at ruppees 3 per m.

Answer 1

let the ratio constant be x
so sides are 4x and 3x
area of rectangular park=length*breadth
2028=4x*3x
2028=12x^2
2028/12=x^2
169=x^2
√169=x
13=x
4x=4*13
=52
3x=3*13
=39
perimeter =2(l+b)
=2*(52+39)
=2*91
=182m
fencing=3*182
Rs.526

Answer 2

let the ratio constant be x

so sides are 4x and 3x

area of rectangular park=length*breadth

2028=4x*3x

2028=12x^2

2028/12=x^2

169=x^2

√169=x

13=x

4x=4*13

=52

3x=3*13

=39

perimeter =2(l+b)

=2*(52+39)

=2*91

=182m

fencing=3*182

=546
