I think you're a bit confused. The area of a right triangle is 1/2 base * height which you already know. The problem only gives you the hypotenuse and the base. You need to calculate the height before calculating the area. You can use the Pythagorean theorem to calculate the height pretty easily.

Both of them are wrong?

Shane_BBest ResponseYou've already chosen the best response.1
Yes, both are wrong. The height in the first one does come out to be 7.14 though...but you have then calculate the area.

Alright. So for the first one, A=1/2(7.14) times what? 15 or 9?

Shane_BBest ResponseYou've already chosen the best response.1
For the first one: \[a^2+b^2=c^2\]\[7^2+b^2=10^2\]\[b^2=51\]\[b=7.14\] \[A=\frac{1}{2}(7)(7.14)=?\]The second one is answered the same way

Where do you get 7?

Shane_BBest ResponseYou've already chosen the best response.1
The first problem states that the leg (base) length is 7.

Nvm, I got confused. Sorry.

marcoduuuhBest ResponseYou've already chosen the best response.1
So for the first one: A=599.76

Did you put the above in a calculator? That's not even close :/

You should get an area of ~25

marcoduuuhBest ResponseYou've already chosen the best response.1
Oh wait! I put it in wrong, I got Area=24.99

Shane_BBest ResponseYou've already chosen the best response.1
That's correct :) Now just do the second one the same way

For the second one, I used the Pythagorean theorem and I got B=13.6015?

Btw thank for all the help and patience! @Shane_B

Neverming..windows calculator mistake. Yep, that's correct.

marcoduuuhBest ResponseYou've already chosen the best response.1
Okay so now, the answer should be A=142.8158?
 one year ago

Shane_BBest ResponseYou've already chosen the best response.1
The base of the triangle is 16 and you calculated the height to be 13.6015. So the area should be:\[A=\frac{1}{2}bh=\frac{1}{2}(16)(13.6015)=108.812\]

Oh! That's what I did wrong. I used 21 instead of 16. Thank you so much.
