Answer 1

For fencing she will need to know the perimeter of the garden.
$perimeter = length \times breadth \\ = 20 \times12 \\ = 420 \: m$
Therefore, the cost of fencing=420×150
=63000 rs

Hope this answer your question and please mark me as brainliest

Answer 2

For perimeter of garden (Triangle). =

20m + 12m + 12 m

= 44 m

therefore cost = Rate * perimeter

= 44*150
