Question

A farmer builds a fence for his chickens in the shape

Answer 1

Answer:

The highway fence cost $600.

Step-by-step explanation:

Since the highway fence is twice as cost as the one of the other 4 sides, this means that the highway fence = 2 normal fence.

Therefore, we use

$1800 / highway fence(2 normal fence) + 4 normal fence

$1800 / (2 + 4) = $300

This means that every normal fence cost $300.

Which then we get the highway fence is $600 because it costs double of the normal fence.
