Hi there!

We can find the area of a triangle with the formula:
[tex]area = 0.5 \times base \times height[/tex]

Filling in this formula gives us the following answers.

Triangle 1
[tex]area = 0.5 \times 5 \times 8 = 20[/tex]

Triangle 2
[tex]area = 0.5 \times 7 \times 9 = 31.5[/tex]

Triangle 3
[tex]area = 0.5 \times 16 \times 12 = 96[/tex]

A=bh divided by 2!!

1. A=1/2(8)(5)
So A equals: 20.

2. A=1/2(9)(7)
So A equals: 31.5.

3. A=1/2(16)(12)
So A equals: 96.

Hope this helps!
