Question

find the area of trapezium whose height is 12m and parallel sides are 20m , 10m.
​

Answer 1

180m²

Step-by-step explanation:

A=a+b

2h=20+10

2·12=180m²

Answer 2

Answer:

180m²

Step-by-step explanation:

$\frac{sum \: of \: parallel \: sides}{2} \times h$

$= \frac{20 + 10}{2} \times 12$

$= \frac{30}{2} \times 12$

$= 15 \times 12$

$= 180 {m}^{2}$
