Question

the parallel sides of a trapezium are 20m and 30m and it's non parallel sides are 6m and 8m.Find the area of the trapezium.(It's answer is120m^2)​

Answer 1

Answer:

s = a +b+c+d/2

A = (a + b.)/(a-b) V (s-a)(s-b)(S-b-C)(s-b-d)

S=20+30+6+8/2=64/2=32

A=20+30 / 30-20V/12x2x(32-20-6)

x (32-20-8)

A=50/10 V24x6x4=5x24=120cm2
