The perimeter is the total distance of the sides of the rectangle. Since parallel sides in a rectangle are equal, we can calculate the perimeter using the length and width given. The area can be found by multiplying the length by the width.
(a)
Perimeter: 2l + 2w = 2(77 yd) + 2(24 yd) = 154 yd + 48 yd = 202 yd.
Area: 77 yd × 24 yd = 1848 yd².

(b) To determine how long it will take to walk around the field, one would need to know the total distance of the edges that make up the field. That would be the perimeter, which is the measure that would be used here.

(c) To determine the amount of turf needed to cover the field, one needs to know the size or extent of the surface of the region to be covered. That is the definition of area, which is the measure that would be used here.
