I'm not sure... I may get the question wrong. You should probably use this formula A=1/2 BH

3. anonymous

This is my first time doing this I need like a step by step on how to do it

4. anonymous

Hmm, I'm sorry.. I dont get it either lol really wish I did.. but it's confusing

5. calculusxy

Use the Pythagorean Theorem $a^2 + b^2 = c^2$

For question 1 we know that a = 16 and b = 63 so let's plug that into the formula to find c (hypotenuse) $16^2 + 63^2 = c^2$

8. anonymous

16^2 + 63^ =c^2 lol

9. calculusxy

Do you understand how to find the answer to this problem?

10. anonymous

4,225?

11. calculusxy

Good and then find the aquaria root of 4,225 because when c is being squared, it equals to 4225.

12. calculusxy

*square root

13. anonymous

65

14. calculusxy

correct!

15. anonymous

Thank you can you wait until I do the second problem so i can see if its right?

16. calculusxy

Sure !

18. calculusxy

Let's check! $a^2 + 2.1^2 = 2.9^2$ $a^2 = 4$ (because 2.9^2 - 2.1^2) $a = \sqrt4$

19. anonymous

ohhh okay! I just plugged it in wrong

20. anonymous

Thank you! I'll contact you if i need help with anything else

21. calculusxy

Sure! and You're welcome :)
