Answer 1

Step-by-step explanation:

let me go step by step

now given

perimeter=540metres

cost of ploughing=18.80per10square metres

solution--------

let x be a common multiple of 25,17,12

so sides will be 25 x 17x 12x respectively

now according to condition

54x=540

x=10

so

sides are 250,170 and 120metres respectively

so area you can find by herons formula

then use it to find cost
