    Area Triangle
Click For Summary
To find the smallest possible area of a right triangle with base and height measurements of 2.7 cm and 3.4 cm, both rounded to one decimal place, the base could be as low as 2.6 cm and the height as low as 3.3 cm. The area is calculated using the formula (1/2) base times height. Substituting the minimum values, the smallest area would be (1/2) * 2.6 cm * 3.3 cm. This results in an area of 4.29 cm².

Hi,

I'm trying to work out this question, and the answer I'm coming up with isn't right. Can anyone help me understand the calculation used to work this out?

I can't read that nor enlarge it. Can't you just type the probelm in?

Yes, sorry it's not larger in the browser. The question is, in this right angled triangle, both measurements (2.7cm and 3.4cm) are given correct to 1 decimal place (d.p). What is the smallest possible area of the triangle?

Thank you :)
 
Okay. I presume you know that the area of such a right triangle is (1/2) base times height. Since the base is 2.7 cm "given to one decimal place", it could be as low as 2.6 cm. The height is 3.4 cm "given to one decimal place" so it could be as low as 3.3 cm. Now can you calculate the smallest area?
 

Thread 'Leibniz Rule Videos on Digital-University'

Good morning I have been refreshing my memory about Leibniz differentiation of integrals and found some useful videos from digital-university.org on YouTube. Although the audio quality is poor and the speaker proceeds a bit slowly, the explanations and processes are clear. However, it seems that one video in the Leibniz rule series is missing. While the videos are still present on YouTube, the referring website no longer exists but is preserved on the internet archive...
