4. A rectangular park has been constructed in

downtown Lilburn. The designer wants to put a gravel

walkway that cuts diagonally through the park. The

width is 8 ft and the height is 6 ft long. What is the

length of his walkway?

10ft

Step-by-step explanation:

Think of the rectangle as two right triangles. Sides a and b on the triangle are 8ft and 6 ft.  That's 8 squared + 6 squared = c squared.  C is 10 ft.
