Question

A sidewalk is to be placed completely around a rectangular playing field that measures 110 yards by 200 yards. What is the length of the sidewalk, in yards?

a) 220
b) 310
c) 420
d) 510
e) 620

Answer 1

The length of the sidewalk around the rectangular playing field is 620 yards, calculated using the perimeter formula for a rectangle.

Step-by-step explanation:

To find the length of the sidewalk that surrounds the rectangular playing field, we need to calculate the perimeter of the rectangle. The formula to find the perimeter of a rectangle is 2(length + width). In this case, the length of the playing field is 110 yards and the width is 200 yards.

We calculate the perimeter as follows:

Perimeter = 2(110 yards + 200 yards) = 2(310 yards) = 620 yards.

Therefore, the length of the sidewalk that will be placed around the playing field is 620 yards, which corresponds to answer choice (e).
