Question

Find the area of Field ABCDEFGH given aside in which BC=28m,BG=21m, AM=18,DN=12.8,ED=14m.​

Answer 1

Area of field = 1002 m²

Step-by-step explanation:

Since BCFG is a rectangle, area = length × breadth = BC* BG = 28 * 21 = 588 m² ---------------------(1)

Area of △ABG = 12 * base * height = 12 * 21 *18 = 189 m² ---------------------(2)

Area of trapezium EDCF=12 (Sum of parallel sides) * height = 12 * (ED+ FC) * ND = 12 * (21+14) * 12.8 = 6.4 * 35 = 225 m² ---------------------(3)

Area of the given figure = sum of 1, 2 and 3 =  189 + 225 + 588 = 1002 m².
