Question

26.) A rectangular park has length and breadth in the ratio 9:7. The total cost of fencing the park is Rs
64,000 at the rate of 200 per metre. What are the dimentions of the plot?
​

Answer 1

Answer:

length = 90metre

breadth = 70 metre

Step-by-step explanation:

cost of fencing = 64,000

rate of fencing per metre = 200

so perimeter = 64000/200 = 320m

let the length be 9x metre and breadth be 7x metre

perimeter = 2(9x+6x)meter = 32x metre

but perimeter is 320 metre

so, 320 = 32x

x= 10

length = 9 x 10 = 90metre

breadth = 7 x 10 = 70 metre
