Question

find the area of trapezium the length of whose parallel sides are 16 cm and 20 cm and the distance between them is 12 CM​

Answer 1

area =1/2 ×h(a+c)
area =1/2 ×12 (16+20)
= 1/2 ×12 (36)
=1/2×12×36
=6×36
=216sqcm is answer

Answer 2

Area of trapezium is 1/2*(b1+b2)*h

So,1/2*(16+20)*12

1/2*36*12

216 cm^2
