Question

sides of rectangular park are in ratio 3:2.If it's area is 1536 msquare then cost of fencing it at rd 350 metre

Answer 1

Let the sides be 3x and 2x

1536m^2 = 3x × 2x
1536m^2 = 6x^2
square root of 1536 = 6x
39.19 = 6x
x = 39.19÷6
x = 6.5m

3x = 3 × 6.5
= 19.5m

2x = 2 × 6.5
= 13m


we have to find the cost of fencing

Perimeter = 2 (13 + 19.5)
= 2 (32.5)
= 65m

1m = Rs 350
65m = 350 × 65
= Rs 22750

Answer 2

Answer:

x + 8x/100 = 769

108x/100 = 769

x = 76900/108

x = 712.03
