1.	In given tigure ABCD is a trapezium in which AB l DC and DA L AB. If AB13 cm,AD 8 cm and CD 7 cm, then find area of trapezium.13
Answer» Area of trapezium= 1/2 × sum of parallel sides× height.= 1/2 × ( AB + CD ) × AD= 1/2 × ( 13 + 7 ) × 8 = 1/2 × 20 × 8 = 10 × 8= 80 cm² Area = 0.5heightsum of parallel sides= 0.58(7+13)= 0.5820= 8*10= 80 sq cm

In given tigure ABCD is a trapezium in which AB l DC and DA L AB. If AB13 cm,AD 8 cm and CD 7 cm, then find area of trapezium.13

Answer»

Area of trapezium= 1/2 × sum of parallel sides× height.= 1/2 × ( AB + CD ) × AD= 1/2 × ( 13 + 7 ) × 8 = 1/2 × 20 × 8 = 10 × 8= 80 cm²

Area = 0.5*height*sum of parallel sides= 0.5*8*(7+13)= 0.5*8*20= 8*10= 80 sq cm
