Question

Find the area of the trpezium whose parallel sides are 12 cm and 18cm and the distances between them is 9cm​

Answer 1

Answer:

135 cm²

Step-by-step explanation:

Area of trapezium = 1/2 × (sum of parallel sides) × distance between the parallel sides

Sum of parallel sides = 12cm + 18cm = 30cm

distance between the parallel sides = 9cm

1/2 × 30 × 9

15 × 9

135 cm²

Hence, the area of trapezium is 135cm²

Answer 2

Given :-

Parallel sides of the trapezium = 12 cm and 18 cm

Distance between them = 9 cm

To Find :-

The area of the trapezium.

Analysis :-

Substitute the given values in the formula of area of trapezium.

The number you get after solving it is your area.

Solution :-

We know that,

• b = Base
• h = Height
• a = Area

By the formula,

$\underline{\boxed{\sf Area \ of \ trapezium= \dfrac{a+b}{2} \times h }}$

Substituting their values,

= 12 + 18/2 × 9

= 30/2 × 9

= 15 × 9

= 135 cm²

Therefore, area of the trapezium is 135 cm².
