No
The perimeter of an object is simply the length of its border, so the perimeter of a triangle is the sum of the lengths of its 3 sides.The area of a triangle is equal to half of its base times its height, for example if a triangle had a base of length 4 and was 5 units tall, it would have an area of (4*5)/2, or 10 units2.
No because the sum of the smaller lengths must be greater than the longest length
Area = 0.5*10*4 = 20 square units
A scalene triangle.
If its a right angle triangle then its side lengths could be 3, 4 and 5
Yes and it will be a scalene triangle
No
If you double them all it will be 4 times the area

11, 4, 8
No because the sum of the smaller lengths must be greater than the longest length
Area = 0.5*10*4 = 20 square units
A scalene triangle.
Yes and the given lengths would form an isosceles triangle.
Yes, it is.
A triangle is half a square The area of a square is height × width(base) So, the area of a triangle is height × base ÷ 2 5×4÷2 = 10
