Post count: 573 a. Draw a field diagram of the block of land represented by the notebook entry. b. Calculate the area of this block of land. a. draw the offsets on the left and right, including each measurement going up, starting at 30, then (60 – 30) = 30 (75 – 60) = 15 (95 – 75) = 20 b. A1 = ½ × 95 × 40 = 1900 find the area of the triangle on the right: base = 95 and height = 40 A2 = ½ × 70 × 20 = 700 Area of the top triangle on the top left: base = 70 and height = 20 A3 = ½ × 45 × (70 + 36) = 2385 Area of trapezium with height 45 and parallel sides 70 and 36 A4 = ½ × 30 × 36 = 540 Area of bottom triangle on the left: base = 30 and height 36 A = 1900 + 700 + 2385 + 540 = 5525m2 add to find the total area
