Find the area of trapezium when two parallel sides are 1 cm and 2 cm respectively and two non parallel sides are 1 cm each and height is given as 0.9 cm *

1.35 cm^2
2.9 cm^2
3.4cm^2
4.5cm^2​

Answer 1

Answer:

1.35 cm²

Step-by-step explanation:

area of trapezium = $\frac{1}{2} \: \times (sum \: of \: parallel \: side) \times height$

$\frac{1}{2} \times (1 + 2) \times 0.9 \\ \frac{1}{2 } \times 3 \times 0.9 \: \: \: \: \: \: \: \: \: \: \: \\ 1.5 \times 0.9 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ 1.35cm {}^{2} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$
