What is the formula of the area and perimeter of a triangle?

Area = 0.5 x base x height Perimeter = side 1 + side 2 + side 3 Formula for Area of a triangle is A = bh/2, where A is Area, b is base, and h is heigth. Formula for finding the perimeter is P = s1 + s2 + s3, where s represent side, or P = AB + BC + AC where the letters represent the sides.

What is the formula for a tiangular pyramid?

The volume of a triangular pyramid can be found using the formula Volume=Base Area x height /3. Surface Area can be expressed as Surface Area =Base Area+0.5 x perimeter x side length.


What is the area of a rectangle that is a perimeter of 30?

It can be 56.25 or anything less, but not more. You can't tell the area from the perimeter, and you can't tell the perimeter from the area. -- if each side is 7.5, the perimeter is 30, and the area is 56.25 -- if it's (5 by 10), the perimeter is still 30, and the area is 50 -- if it's (4 by 11), the perimeter is still 30, and the area is 44 -- if it's (3 by 12), the perimeter is still 30, and the area is 36 -- if it's (2 by 13), the perimeter is still 30, and the area is 26 -- if it's (1 by 14), the perimeter is still 30, and the area is 14


Calculate the area and the height of an equilateral triangle whose perimeter is 60 cm?

It will have 3 equal sides of 20cm Using Pythagoras's' theorem its height is 17.32050808cm Using the formula for area:1/2*base*height its area is 173.32050808cm2
