【Answer】: 2. a. Trapezoid b. 10 m, 15 m, 35 m, 40 m c. Perimeter = Sum of all sides d. 100 m3. a. Rhombus b. 60 cm c. Perimeter = 4 * side d. 240 cm【Explanation】: 2. a. The shape of the lot is a trapezoid because it has one pair of parallel sides. b. The measurements of the sides are given as 10 m, 15 m, 35 m, and 40 m. c. The formula for finding the perimeter of any polygon is to add up the lengths of all its sides. d. Adding up the given measurements, we get 10 m + 15 m + 35 m + 40 m = 100 m. So, the perimeter of the lot is 100 m.3. a. The shape of the working table is a rhombus because all its sides are equal. b. The measurement of one side of the rhombus is given as 60 cm. c. The formula for finding the perimeter of a rhombus is to multiply the length of one side by 4. d. Multiplying the given measurement by 4, we get 60 cm * 4 = 240 cm. So, the perimeter of the working table is 240 cm.
