You can put this solution on YOUR website! A diagnol walk through a small rectangular garden 9 meters by 12 meters can be built at $10 per linear meter. How much will the walk cost?
.
Draw a diagram of your problem.
Once you do, you'll see that you need to find the length of the diagonal.
To do this, you need to apply Pythagorean Theorem.
.
Length of diagonal:
sqrt(9^2 + 12^2)
= sqrt(81 + 144)
= sqrt(225)
= 15 feet
.
Since the cost is $10 per linear feet:
10*15 = $150
