Answer:Draw a parallel line from DE intersecting AB at G.
So AGEF is a rectangle with length 1.2m & Breadth 0.3 m
Area= LxB= 1.2x0.3=0.36 cm2
CDGB is a trapezium with parallel sides on length 0.6 & (1.8-0.3)= 1.5 m with distance between them as GD= DE+ EG=0.8+1.2 m= 2.0 m
So Trapezium Area is 1/2x(0.6+1.5)x2.0
Viz 2.1 M2
So total area is Rectungular Area of AGEF added to Trapezium CDGB
0.36+2.1 m2
2.46 m2
Step-by-step explanation:
Answer:
4.5 is the area of the cross-section
