Question

the area of the trapezium whose height is 14cm and the parallel sides are 18cm and 9cm is*​

Answer 1

Answer:

length of parallel sides = 14 and 18cm

dist btw parallel sides =9cm

Area of trapezium = 1/2 * height * (sum of parallelsides)

                           = 1/2 * 9 * ( 14 + 18 )

                           = 1/2 * 9 * 32

                           = 9 * 16

                           = 144 cm(square)

Answer 2

Answer:

Area of the trapezium is 189 cm ².

Step-by-step explanation:

Given :

Height of trapezium = 14 cm

One parallel sides of trapezium = 18 cm

Second parallel sides of trapezium = 9 cm

Find :

The area of the trapezium

Solution:

The parallel sides are 18cm and 9cm

So,

By using the formula

The area of trapezium =

⇒ 1 / 2 × ( sum of parallel sides ) × height

⇒ 1 / 2 × ( 18 + 9 ) × 14

⇒ 1 / 2 × 27 × 14

⇒ 1 × 27 × 7

⇒ 1 × 189

⇒ 189 cm²

Therefore, the area of the trapezium is 189 cm ².
