Since I'm not sure what shape you need I will give you these.
Triangle
1⁄2 b*h
b=base
h=height
b=base h =height
Rectangle
length * width
Trapezoid
1⁄2 h ( b_1+ b_2 )
h = height
b_1=base 1
b_2=base 2
Square
s^2 s =side
Parallelogram
base * altitude
Pentagon
1⁄2 a*p
a = apothem
P = perimeter
Hexagon
1⁄2 a*p
a = apothem
P = perimeter
Heptagon
1⁄2 a*p
a = apothem
P = perimeter
Octagon
1⁄2 a*p
a = apothem
P = perimeter
Hope this helped you! I would appreciate a brainliest!
