Question

2) Length of the two parallel sides of a trapezium are 9.5cm and 11.5cm respectively. Its height
is 4.6cm. Find its area.​

Answer 1

Answer:

Given:-

• Length of parallel sides = 9.5 cm and 11.5 cm respectively.
• Height = 4.6 cm

To find:-

Area of the trapezium

Solution:-

We know that, area of a trapezium =

$\bf {\dfrac{1}{2} \times (a+b) \times h}$

Now, substituting values in the above formula;

Area = ½ × (9.5 + 11.5) × 4.6

= ½ × 21 × 4.6

= 21 × 2.3

= 48.3 cm²

Hence, area of the trapezium is 48.3 cm².

Answer 2

Answer:

$formula \: of \: area \: trapezium \: is = \frac{1}{2} \times height \times (sum \: of \: parrel \: lines)$

Explanation:

$= \frac{1}{2} \times 4.6 \times (9.5 + 11.5)cm \\ = \frac{1}{2} \times 4.6 \times 21.0 cm\\ = \frac{1}{2} \times 96.6 cm\\ = 32.2cm2$

$answer = 32.2cm2$
