So, what is the formula for area of a triangle?
anonymous
  • anonymous
a2 +b2= c2 and a= 1/2 bh.

ok, so we have the height. We want to find the base length to plug into the area formula Of course, you went a step ahead and gave the next formula as well. We would have to use Pythagorean Theorem to determine the length of the base. a^2 + b^2 = c^2

  • anonymous
So would it be a2 +8^2 =7^2
AccessDenied
  • AccessDenied
In a^2 + b^2 = c^2, the a^2 and b^2 represent the squared lengths of the legs of the triangle. The c^2 represents the hypotenuse length squared. |dw:1337037273817:dw|

  • AccessDenied
So you'd have 7^2 + b^2 = 8^2. We'd solve for b there.

Ok so it would be 7^2 + b^2 = 8^2?
AccessDenied
  • AccessDenied
Yeah. :)
AccessDenied
  • AccessDenied
Once we find b there, we round it to the nearest tenth and then apply it in the area formula with the height 7 and that as the base.

So what would the total answer be for the a2 + b2 = c2?
AccessDenied
  • AccessDenied
7^2 + b^2 = 8^2 49 + b^2 = 64 b^2 = 15 b = sqrt{15} then you can evaluate this in calculator to round it to nearest tenth

  • anonymous
I typed it in and squared rooted it and I still got 15
AccessDenied
  • AccessDenied
Hm maybe it was typed in wrong. I get sqrt(15) ~ 3.87298
anonymous
  • anonymous
So would the round to 4?
AccessDenied
  • AccessDenied
we round it to nearest tenth, so we look at the 3.87 and determine whether to keep 3.8 or go to 3.9
anonymous
  • anonymous
We would keep it at 3.9?
AccessDenied
  • AccessDenied
Yes, we use 3.9. So, just plug it into area formula \(A = \frac{1}{2} b h \) with b = 3.9 and h = 7 and solve for A. It looks like you have to round the value of A to nearest tenth also.
AccessDenied
  • AccessDenied
So, what I get is A = 1/2 (3.9) (7) = 13.65 = 13.7 rounded up to nearest tenth.
