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
Answer:
○ B. 
Step-by-step explanation:
All sides meet at right angles, so when split up, you have this:

Answer:
7.92 cubic units
Step-by-step explanation:
The volume formed is V = ∫πx²dy
Now, since y = x³/4, x = ∛(4y). Also if x = 0, y = 0³/4 = 0 and the curve intersects the line y = 1. So the limits of integration are y = 0 to y = 1
So, V = ∫₀¹πx²dy
= ∫₀¹π[ ∛(4y)]²dy
= π(∛4)²∫₀¹[ ∛(y]²dy
= π(∛4)²∫₀¹y^³/₂dy
= π(∛4)²[y^⁵/₂]₀¹
= π(∛4)²[1^⁵/₂ - 0^⁵/₂]
= π(∛4)²[1 - 0]
= π(∛4)²
= 7.92 cubic units
