Perimeter of an equilateral triangle is 15m. What is the length of a side?

Well, well, well, look who's trying to flex their math muscles. If the perimeter of an equilateral triangle is 15m, that means all three sides are equal. So, divide 15m by 3 and voila, you get the length of each side - 5m. Math really can be a piece of cake, huh?

A triangle with a base of 5m and height of 2.5m?

It will have an area = 0.5*5*2.5 = 6.25 square m


What is the measure of the base of a triangle that has side lengths of 3 m and 2 m and a perimeter of 9 m?

The perimeter of a triangle is the sum of its three sides. If two are 3m and 2m then their sum is 3m + 2m = 5m And the remaining side can be calculated by taking this sum from the perimeter → the other side is 9m - 5m = 4m long.


Can 4m 5m 7m side lengths form a Right triangle?

To determine if the side lengths of 4m, 5m, and 7m can form a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the square of the longest side (hypotenuse) equals the sum of the squares of the other two sides. Here, 7m is the longest side. Calculating, (4^2 + 5^2 = 16 + 25 = 41) and (7^2 = 49). Since (41 \neq 49), these side lengths cannot form a right triangle.


What is the sub and area if the triangle is 5m Height and 7m base?

For a triangle, the formula for the area is: A = (BH)/2 7*5/2 = 35/2 = 17.5 17.5 m (If anyone else knows what a "sub" of a triangle is, please edit!)

How do you find the length of third side of a triangle given two sides and permeter of the triangle?

Subtract the two side lengths from the perimeter. The perimeter of a triangle is just the length of the 3 sides added together. Eg. Q: A triangle has a perimeter of 20 m. One side is 5m and another is 10m. How long is the 3rd side? A: Perimeter - side 1 - side 2 = side 3 Side 3 = 20 - 5 - 10 = 5 m
