The area of a triangle (At) is one half the length of the base (b) times the height (h).
Atriangle = 0.5bh
The height of a triangle is the length of the line drawn perpendicular (at right angles to) to the base from the angle opposite the base.
The area of any triangle has the same formula, which is base times height, divided by 2. A scalene triangle is a triangle with three sides of unequal length, which is not important when calculating the area.
There are at least 8 different "measures" that we can think of for any triangle: three sides, three angles, a perimeter, and an area. We can't guess which one you're looking for. A 'scalene' triangle is simply any triangle in which no two sides are the same length. That fact doesn't help us.

If another triangle has the same three sides, that is, sides of the same length, it will have the same area. Note that this is a sufficient, but not a necessary, condition, since you can also have triangles of a different shape that have the same area.
There is only one basic shape for an equilateral triangle. The area can only vary as the length of the sides vary.
Area of Triangle when the length of the three sides is known: square-root [P * (P-2a) * (P-2b) * (P-2c)] / 4 where P is total perimeter and a, b and c are the lengths of the three sides.
By definition, an equilateral triangle has all three sides of equal length! So it is impossible for it to have sides of length 10 inches and 7 inches!
The area of any triangle has the same formula, which is base times height, divided by 2. A scalene triangle is a triangle with three sides of unequal length, which is not important when calculating the area.

Area of the square if 36 cm2ExplanationSince a square has 4 sides of equal length, we solve this problem by finding the perimeter of the triangle and dividing that number by 4.We are given the lengths of the 3 sides so the perimeter is their sum. Sine the perimeter of the triangle is 24, we know the each side of the square is length 6.The area is 62 or 36
It depends on the length of the other two sides !

Like all triangles , a Scalene triangle has three sides, aand the sum of the angles adds to 180 degrees. In a Scalene triangle all three angles are of different size. The Classes of triangles are: Equilateral ; All sides of equal length ; all angles are 60 degrees. Isosceles ; Two sides of equal length ; two angles the same size. Right-Angled ; Two sides of equal length or all three sides of different length ; one angle at 90 degrees. Scalene ; All three sides of different length ; all three angles of different size. As for a formula ; The Area of a triangle is euql to one halfe the base multiplied to the perpendicular height. A = (1/2)bh or A = (0.5)bh
If another triangle has the same three sides, that is, sides of the same length, it will have the same area. Note that this is a sufficient, but not a necessary, condition, since you can also have triangles of a different shape that have the same area.
add up the length of all the sides
It is a plane area enclosed by three straight sides.
