Question

The lengths of the parallel
sides of a trapezium is 18
cm and 22 cm. The distance
between the parallel sides is
15 cm. What is the area of
the trapezium?​

Answer 1

Answer: A= (18+22)÷5= 8 cm2

Answer 2

Answer:

Given

• Length of the parallel sides = 18cm and 22cm
• The distance between the parallel sides = height of the trapezium = 15cm

Now, Area of trapezium

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

Substituting the value

we get area of the trapezium

$= \frac{(18 + 22)15}{2} \\ = \frac{40 \times 15}{2} \\ = 20 \times 15 \\ = 300cm {}^{2}$
