if the triangle was an equilateral triangle, you would have been able to just multiply 45 with 3... but if the triangle was some other kind of triangle, you would have to know the other sides
24 inches You can find the perimeter of a triangle by adding the lengths of all three sides. In this case, since the triangle measures 6, 8, and 10 inches, its perimeter would be the sum of these numbers which is 24 inches.
4 inches x 3 sides = 12 inches for the perimeter.
Find the area of an equilateral triangle that has a perimeter of 21 inches. Round the answer to one decimal place.
To find the perimeter of a triangle, add the three sides. Perimeter = 6in + 8in + 10in = 24in.
Let x be the side of the triangle. Thus 4(x-5) is the perimeter of the square.Balance by the perimeter relation,3x = 7+4(x-5)Solve for x,x = 13 inches
50 in
To find the perimeter you just add up the sides. So it would be 24 inches.
The perimeter of a triangle is the distance around it. Add the lengths of the three sides to find the perimeter.
There is no reason for the perimeter of a triangle to have any relation to the perimeter of an unrelated rectangle!
the answer is 32
You add the lengths of all the sides together. For an example, if the sides of a triangle were: 2 inches, 3 inches, and 5 inches, you would add 2, 3, and 5 together to get 10 inches.
If you know the perimeter, there is no need to find it again.
