Question

14. The base of a parallelogram is 20 cm and its area is 246 sq. cm, then its altitude is :
(a)12.5 cm (b) 10.5 cm (c) 12.3 cm (d) 12.4 cm
​

Answer 1

Answer:

246=20xh

246/20=h

h=12.3cm

Step-by-step explanation:

Answer 2

Question:-

The base of a parallelogram is 20 cm and its area is 246 sq. cm, then its altitude is :

(a)12.5 cm (b) 10.5 cm (c) 12.3 cm (d) 12.4 cm

Answer:-

• The Altitude is 12.3 cm

To find:-

• The Altitude of parallelogram

Solution:-

• Base of parallelogram = 20 cm
• Area of parallelogram = 246 cm²
• Altitude = ?

As we know,

$\mathfrak{ \huge{area = base \times height}}$

According to question ,

$\large{ \tt : \implies \: \: \: \: \: \: 20 \times height = 246}$

$\large{ \tt: \implies \: \: \: \: \: \: height = \frac{246}{20} }$

$\large{ \tt: \implies \: \: \: \: \: \: height = 12.3 \: cm}$

Hence,

The height of parallelogram is 12.3 cm

$\therefore{ \tt{ \underline{The \: correct \: option \: is \: (c)}}}$
