Question

The park near John's house is being sprayed for mosquitoes. He and his neighbor are roping off the park so kids don't go near the part being sprayed. The park is shaped like a rectangle with a length of 42 yards and a width of 36 yards. How much rope do they need?

Answer 1

If you would like to know how much rope do they need, you can calculate this using the following steps:

42 yards * 2 + 36 yards * 2 = 42 * 2 + 36 * 2 = 84 + 72 = 156 yards

They will need 156 yards long rope.
