To find the perimeter of the base, you must add all the numbers on the base together!
Height = (Perimeter/2) - Base
perimeter (P)=2(length+base) find length, area = length * base = (p/2-base)*base
2*(base) + 2*(height) = perimeter
The same way you find the perimeter of a rectangle, add the side lengths
To find the perimeter of a rectangle simply add the length and width then double your answer.
Assuming that neither of the sides of equal length is the base, Perimeter = Base + 2*Slanted sides.
12 the base times the height
12 the base times the height
It is: perimeter minus hypotenus+base = height Area = 0.5*base*height
1/2 AP where A=apothem and P= perimeter
im pretty sure its base*height squared
2*area of a base + length*perimeter of base.
