Question

2. A room is triangular in shape. Its base is 9.4m and height is 8.6m. Find the cost of its
wooden floor at the rate of Rs. 250 per square meter

Answer 1

Answer:

Cost of wooden floor @ Rs250 per m^2 = Rs.10105

Answer 2

Given :

⬤ Base of Triangle is 9.4 m .

⬤ Height of Triangle is 8.6 m .

To Find :

⬤ Cost of its Wooden floor at the Rate of Rs. 250 per m² .

Formula Used :

$\bf[\:{Area\:of\: Triangle=\dfrac{1}{2}\times{b}\times{h}}\:]$

• b = base
• h = height

Solution :

According to the Formula :-

1/2 × base × height

1/2 × 9.4 × 8.6

1/2 × 94/10 × 86/10

4042/100

40.42

Therefore , The Area of Triangle is 49.42 m² .

Now :

As given that , We have to Find Cost of its Wooden floor at the Rate of Rs. 250 per m² . Hence ,

40.42 × 250

10105

Therefore , Cost of its Wooden Floor at the Rate of Rs. 250 per m² is 10105 .
