Here we will learn how to use the formula to find the area of trapezium.
Area of trapezium ABCD = Area of ∆ ABD + Area of ∆ CBD
= 1/2 × a × h + 1/2 × b × h
= 1/2 × h × (a + b)
= 1/2 (sum of parallel sides) × (perpendicular distance between them)////// I think this will help you

Answer:
Step-by-step explanation:
Area of a trapezium=1/2*sum of parallel side *height.
→60=1/2*(6+4)*height
→60=1/2*20*height
→60=10*height
→6/10=Height
→6=height
LC=DC-AB
LC=(14-6)cm
LC=8cm
By pythagoreas theorem,
BC^=BL^+LC^
BC^=6^+8^
BC^=36+64
BC^=100
BC=root over 100
BC=10
