Question

The perimeter of a triangular field is 540 m and its sides are in the ratio 25 : 17 : 12. Find
the area of the triangle. Also, find the cost of cultivating the field at 24.60 per 100 m².​

Answer 1

Answer:

area = 15000

price = 3,690 Rs

Step-by-step explanation:

25x + 17x +12x = 540  

54x = 540  

X = 540/54 = 10  

Therefore x = 10  

The three sides are -  

First side is 25x = 25 multiplied by 10 is equal to 250 .  

Second side is 17x = 17 multiplied by 10 is equal to 170.  

Third side is 12x = 12 multiplied by 10 is equal to 120.

area =1/2×b×h

=1/2×120×250

=250×60

=15000

price = 15000×24.6/100 = 3,690rs
