Question

if the measure of the hypotenuse of a right triangle is 15cm if the base of the triangle measures 9cm. what is te area in square centimeters of the triangle??

Answer 1

im just going to give this to you, and hope that you try to understand it


4 square centimeters
please explain it and ill try to hellp you understand...

Answer 2

dont get it

Answer 3

thats the area???

Answer 4

yeah, its an area... because an area is two dimensional... do you know what that means?

Answer 5

yes i just get how 4 is the area

Answer 6

what don tyou get?

Answer 7

how the area is 4

Answer 8

oh im sorry, the area isn't 4 square cm, thats the length of the side

Answer 9

oh whats the area

Answer 10

you would use the area for a triangle... which woud be base times height/2 so once you have the base height and hypotenuse, you can work it out right?

Answer 11

for base i have 9 h i have 13 and hypotanuse i have15

Answer 12

is that right

Answer 13

no, how did you get that? and ill tell you where you went wrong

Answer 14

i did a2 +b2 = c2 and inputed numbers

Answer 15

which numbers where?

Answer 16

well i was finding a so b was 9 squared and c was 15 squared

Answer 17

ok, that should have worked, what did you do after you had the numbers in (how did you solve it)?

Answer 18

my anwer for a was 13.1

Answer 19

how did you get that?

Answer 20

by just following it through like nine squared is 81 and fifteen squared is 225

Answer 21

then subtrected 81 from both sides to leave a by its self which was 174 the square root of tht is 13.1

Answer 22

oh ok
so look at 225-81 again (its not 174)

Answer 23

ok for area i got 54

Answer 24

yay, but you should say 54 square centimeters... i got 54 square centimeters too

Answer 25

ok thanks
