Answer 2

22 square millimeters

Explanation:

Given,

Parallel sides of the trapezium = 3mm, 8mm

Height of the trapezium = 4mm

Therefore,

Area of the trapezium

`= (1)/(2) * (sum \: of \: parallel \: sides) * height`

`= (1)/(2) * (8 + 3)mm \: * 4mm`

`= (1)/(2) * 11mm * 4mm`

= 11mm × 2mm

`= 22 {mm}^(2)`

Hence,

Area of the trapezium is 22 square millimeters (Ans)
