Answer:
The length of the diagonal walkway is 17 meters (option c)
Explanation:
Hi, having a rectangular area is equal to having two triangles with a common side, the hypotenuse.
In this case, the hypotenuse is also the diagonal length between the opposite corners of the garden.
We have to apply the Pythagorean Theorem: c²= a²+b²
Where c is the hypotenuse, and the other variables are the legs of the triangle, in this case, the width and length of the garden (15 and 8)
So, replacing with the values given:
c²= a²+b²
c²= 15²+8²
c²= 225 +64
c²= 289
c= √289
c = 17
The length of the diagonal walkway is 17 meters (option c)
