Question

find area of trainagle 1 1/4 is base and height is 4/9

Answer 1

area = half of the base * the height

Answer 2

i got 1 1/9 is that correct

Answer 3

No, that's not right. I'm working it out right now

Answer 4

It's equivalent to .277777778

Answer 5

how did you get that

Answer 6

Can you change the base to an improper fraction?

Answer 7

half of 1 and 1/4 is .625. and then multiply that by 4/9 and you get .27777778

Answer 8

phi yes you can

Answer 9

The formula for the area of a triangle is
\[ A= \frac{1}{2} b\cdot h\]
where b is the base and h is the height (or altitude)

the easiest way is to change the base \(= 1 \frac{1}{4}\) to an improper fraction then multiply the fractions b*h
then multiply by 1/2

Answer 10

I know I can. Can you? if so what is it?

Answer 11

5/4

Answer 12

now multiply the fractions
\[ \frac{1}{2}\cdot\frac{5}{4}\cdot \frac{4}{9} \]
multiply tops, and multiply bottoms
(but you can simplify by first cancelling the 4's)

Answer 13

5/4 times 4/9= 20/36 then do i multiply by half

Answer 14

yes

Answer 15

is its 5/18

Answer 16

but notice it is easier to first cancel the 4's
You can do that because order does not matter.
\[ \frac{1}{2}\cdot\frac{\cancel{4}}{\cancel{4}}\cdot \frac{5}{9} = \frac{5}{18}\]

Answer 17

thank you
