## Task 3 - 040623

A rectangular school garden is to be fenced. On each of the shorter sides, which are each 40 m long, there are 21 concrete posts, and on the longer sides, there are 15 more each. The distance between any two adjacent posts is the same. A gate will be installed between two of these posts.

What are the costs if 1 m of fence costs 9.50 MDN, 1 post costs 11.00 MDN, and the gate costs 64.00 MDN?

The thickness of the posts is not taken into account.
$218 \mathrm{~m}$ of fence cost 2071 MDN, 1 gate costs 64 MDN and 110 concrete posts cost 1210 MDN. In total, this is 3345 MDN.
