Find the area of each triangle.

lord [1]

Hi there!

We can find the area of a triangle with the formula:
$area = 0.5 \times base \times height$

Filling in this formula gives us the following answers.

Triangle 1
$area = 0.5 \times 5 \times 8 = 20$

Triangle 2
$area = 0.5 \times 7 \times 9 = 31.5$

Triangle 3
$area = 0.5 \times 16 \times 12 = 96$

NEED HELP ASAP ON THIS QUESTION

andrew11 [14]

Answer:

None of these answers are correct.

Step-by-step explanation:

If a²+b²=c², then 7²+5²=c², then if you solve for c this equals about 8. This is none of the answers mentioned which is 8. Also, a good thing to remember is that the hypotenuse is always larger than the two side lengths. So, since the answer is 8 then it is none of the answers.
