Find the perimeter and area of a trapezoid: length of top is 2.9 cm; length of bottom (parallel to the top) is 5.8 cm; length of one slant side is 1.7 cm, length of the other slant side is 2.4 cm; and the height is 1.4 cm. Choices are rounded to the nearest tenth. A) P = 14.2 cm; A = 6.1 cm² B) P = 12.8 cm; A = 6.1 cm² C) P = 14.2 cm; A = 2.9 cm² D) P = 10.1 cm; A = 2.9 cm² E) P = 12.8 cm; A = 9.0 cm²

Quizplus · Accepted Answer

The perimeter (P) of the trapezoid is the sum of the lengths of all its sides: 2.9 cm + 5.8 cm + 1.7 cm + 2.4 cm = 12.8 cm. The area (A) of a trapezoid is given by the formula A = 1/2 * (sum of the lengths of the two parallel sides) * height = 1/2 * (2.9 cm + 5.8 cm) * 1.4 cm = 6.1 cm².
