for parallelograms:
area = b(h)
so basically, the length times the height. just like how you would find the area of a square.
perimeter: just add all of the sides together.
for triangles:
area = 1/2(b) x h
so half the length multiplied by the height. for example, if the length was 4, you have to use half of that. so that means 2 times whatever the height is.
perimeter: again, just add all three sides together

Awnser:
I think its 7
Step-by-step explanation:
the photo is blurly can you say it and i can help u again
I think its like if you got 80% on a quiz and 20% on the exam then your grade would be 60% which is usually a F
