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

What would be the area or a regular polygon with a perimeter of 20 feet and an apoyhem of 3 feet?

The formula for finding the area (A) of a regular polygon when its perimeter (p) and apothem (a) are known is: A=(pa)/2 Therefore, when the figures are put into the formula it becomes: A=(20 x 3)/2 A=60/2 A=30 square feet

How do you find the total area of a solid?

To find the total area of a solid, the general formula is SA=(base area)+(perimeter of one face*height). To put it more simply, if you had a cube with edges 3 inches long, your formula would look like this: Area=(3*3)+(6*3), and the answer would be 27 inches squared.


If two shapes have the same perimeter will they have the same area?

Not at all. For example:A square of 2 x 2 will have a perimeter of 8, and an area of 4. A rectangle of 3 x 1 will also have a perimeter of 8, and an area of 3.A "rectangle" of 4 x 0 will also have a perimeter of 8, but the area has shrunk down to zero. The circle has the largest area for a given perimeter/circumference.


What is the formulae fo equalertal triangle?

The formula for the perimeter of an equilateral triangle is P = 3s, where P is the perimeter and s is the length of one side. The formula for the area of an equilateral triangle is A = (s^2 * sqrt(3)) / 4, where A is the area and s is the length of one side.


How does the perimeter and area of a square change when its dimensions change?

A 3 x 3 square has perimeter 12 and area 9 A 6 x 6 square has perimeter 24 and area 36 Double the dimensions, double the perimeter, quadruple the area. Mathematically, a square with side x has a perimeter of 4x and an area of x2 Doubled, a square with side 2x has a perimeter of 8x and an area of 4x2


Can a rectangles perimeter be the same as the area?

Yes, it can because a 3 by 6 rectangle has the perimeter of 18 and has the area of 18! :)
