Answer 1

Answer:

3,564 Rs

Step-by-step explanation:

perimeter of triangular park

= sum of 3 sides

= 30 + 82 + 56

= 168 m

Since we need to leave 6 m space on one side for the gate,

Length of park to be fenced

= 168 - 6

= 162m

cost of fencing per meter = 22 Rs

so cost of fencing the park

= 22 * 162

= 3,564 Rs
