Help me with this question

Pretty sure its 7.5 units²

Step-by-step explanation:

5·3=15÷2=7.5

Doing area with triangles is kind of the same as rectangle, just do base × height. But then divide it by two.

For example: base=3, height=7. With rectangles it would be 21 units².

But with triangles it would be 3·7=21 divided by 2, it would be 10.5 units²

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
