Question

what is the area in square milimeters of a right trangle with a hypotenuse of 68 miilmeters and a leg of 60 milimeters?

Answer 1

area = 1/2 base x ht

Answer 2

use pythagorus theorum to find height

Answer 3

u understand pythag theorum...?@linamireles16

Answer 4

no still dont understand

Answer 5

ok, no worries
you have a right angled triangle, so you're able to use the formula:
\[h^2 = a^2 + b^2\]

where h = hypotenuse
a = ht
b = base

Answer 6

so use h = 68 and b = 60 in the above formula to find a

Answer 7

then use a nd b in:

area = 1/2 base x ht

to find answer

Answer 8

so how'd you go for a?

Answer 9

idid it wrong

Answer 10

i got 1024

Answer 11

ok... what did u do?

Answer 12

for b

Answer 13

thats fine, a^2 = 1024, so what does a = ??

Answer 14

4624=3600+bsquares

Answer 15

sqare rooredd it and got 36 which is not a valid answer

Answer 16

nah, sqrt 1024 = 32 hey

Answer 17

yea you know what i mean ah
any how all my answers are 0000 options

Answer 18

to the thousand

Answer 19

that's cool, you now have a and b, so find area

area of triangle = 1/2 x a x b

Answer 20

a = 32
b = 60

Answer 21

my aswer choices are 2,040
1,920
1,088
960

Answer 22

area of triangle = 1/2 x a x b

a = 32
b = 60

u tell me which is right dude?

Answer 23

\[area = (a \times b) / 2\]

Answer 24

so its 32x60/2?

Answer 25

yep

Answer 26

thanks i got it

Answer 27

what about 65 meters and leg of 25 meters?

Answer 28

sweet, welcome

Answer 29

as for 2nd q, do the same thing
find the verticle height and base length
use that to calculate area

Answer 30

is it 750?

Answer 31

so if you have right angle triangle, one side = base length
one side = verticle height

Answer 32

depends if 65 is hypotenuse or verticle height...?

Answer 33

hypotenuse

Answer 34

cool, so what was vertical height length then...?

Answer 35

idk i just guest

Answer 36

ok... might work but probly not the best approach hey

Answer 37

i got it right

Answer 38

noice! good guess dude

Answer 39

anway whats the approxitmate side lenght of a square with a diagram of 16
