Question

find area of trapezium whose parallel sides are 5cm and 7cm and height is 3cm

Answer 1

Area of trapezium = $\dfrac{1}{2}$ × (sum of parallel side) × (distance between then or height)

= $\dfrac{1}{2}$ × 12 × 7

= 6 × 7

area = $42 cm^{2}$

Answer 2

Given:

• Measure of two parallel sides of trapezium are 5cm & 7cm and the height of the trapezium is 3cm.

To find:

• Area of the trapezium.

Solution:

As we know that,

• Area of trapezium = 1/2 × (Sum of two ∥ sides) × height, therefore,

⇒ 1/2 × (5 + 7)cm × 3cm

⇒ 1/2 × 12cm × 3cm

⇒ 18cm²

Hence, the area of the trapezium is 18cm².
