Hi,

rectangular garden 9 meters by 12 meters

Finding the length of the diagonal d

Applying the Pythagorean Theorem

9^2 + 12^2 = d^2

225 = d^2

+-15 = d   (discarding the negative solution)

15m = d, the length of the diagonal walk

How much will the walk cost at $10/linear meter

15m*$10 = $150
