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
To find the surface area of a three-dimensional object, such as a prism or a pyramid, you can use the formula: Surface Area = Base Area + (Perimeter of the Base × Height). Start by calculating the area of the base, which you already have. Then, multiply the perimeter of the base by the height and add that to the base area to get the total surface area.
im pretty sure its base*height squared
