1a. The perimeter of a rectangle is calculated using the formula P = 2(l + w), where l is the length and w is the width. For a rectangle with length 16 m and width 6 m, the perimeter is P = 2(16 + 6) = 2(22) = 44 m.
2a. The area of a rectangle is calculated using the formula A = l × w, where l is the length and w is the width. For a rectangle with length 20 in and width 13 in, the area is A = 20 × 13 = 260 in².
3a. The area of the rectangle is found by counting the number of unit squares. The rectangle has 5 rows and 8 columns, so the area is 5 × 8 = 40 square units. The perimeter is calculated using the formula P = 2(l + w). The length is 8 units and the width is 5 units, so the perimeter is P = 2(8 + 5) = 2(13) = 26 units.
4a. The perimeter of a rectangle is calculated using the formula P = 2(l + w), where l is the length and w is the width. For a rectangle with length 19 and width 10, the perimeter is P = 2(19 + 10) = 2(29) = 58.
