Question

length of the parallel sides of a trapezium are 8.5 can and 11.5 cm respectively and it's height is 4 .2 can, find its area.

Answer 1

Answer:

Area = 42 cm²

Step-by-step explanation:

Area of a trapezium = 1/2 (a + b) x h

Find the area:

Area = 1/2 ( 8.5 + 11.5) x 4.2

Area = 42 cm²

Answer: Area = 42 cm²

Answer 2

Parallel Side 1 = 8.5 cm
Parallel Side 2 = 11.5 cm
Height = 4.2 cm
$area \\ = \frac{1}{2} \times (Sum \: Of \: Parallel \: Sides) \: \times Height \\ = \frac{1}{2} \times (8.5 \times 11.5) \times 4.2 \\ = \frac{1}{2} \times 20 \times 4.2$
$\boxed{=42cm^2}$
