Answer 2

Answer:

22 square millimeters

Step-by-step explanation:

Given,

Parallel sides of the trapezium = 3mm, 8mm

Height of the trapezium = 4mm

Therefore,

Area of the trapezium

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

$= \frac{1}{2} \times (8 + 3)mm \: \times 4mm$

$= \frac{1}{2} \times 11mm \times 4mm$

= 11mm × 2mm

$= 22 {mm}^{2}$

Hence,

Area of the trapezium is 22 square millimeters (Ans)
