GeometrySHAPES AND FIGURES OF PLANE GEOMETRYExample:Calculate the area and perimeter of a parallelogram with base (b) = 4´,height (h) = 3´, a = 5´ and b = 4´. Be sure to include units in your answer.Solution:A = bh P = 2a + 2bA = (4)(3)P = 2(5) + 2(4)A = 12 square feetP = 10 + 8P = 18 feetA rectangle is a parallelogram with four right angles, as shown in Figure 11.Figure 11 RectangleThe area of a rectangle is calculated using the following formula:A = (length) (width) = lw(3-5)The perimeter of a rectangle is calculated using the following formula:P = 2(length) + 2(width) = 2l + 2w(3-6)The area of a rectangle is always expressed in square units, and the perimeter of a rectangle isalways expressed in the original units.Rev. 0 Page 9 MA-03
