The area of a scalene triangle with any side as base ‘b’ and height ‘h’ (an altitude on that base) is
Q1)Find the area of the triangle with base 20 cm and height 12 cm? Solution:Base (b) = 20 cm Height (h) = 12cm =120cm2
Step 1: If you know the length of the three sides of the triangle (a, b, c). Step 2: Find the semi-perimeter, S. The formula for finding the semi-perimeter of a triangle is Step 3: Then apply the Heron’s formulato find the area of a scalene triangle
Q1)Find the area of a triangle whose sides are 122 cm, 120 cm, and 22 cm. Solution: S= 132 cm Therefore, the area of a triangle is 1320 cm2

Apr 8, 2024 · To find the area of this triangle, you must start by multiplying the base times the height. This will give you the area of a polygon (such as a rectangle). The area of a scalene triangle is half the area of a polygon.
The area of a scalene triangle can be found by using the formula A=\cfrac{1}{2} \, bh, where b is the length of the base of the triangle and h is the perpendicular height of the triangle.
Thus, Area of the scalene triangle, A = √s(s−a)(s−b)(s−c) A = s (s − a) (s − b) (s − c) square units. Here, 's' is the semi perimeter of a triangle which is, s = (a+b+c)/2, and a, b, and c denotes the sides of the triangle. Important Notes.
To find the area of a scalene triangle if we know the length of its base and the corresponding height, we can use the following formula: A=\frac {1} {2}\times b \times h A = 21 × b × h. where b is the length of the base and h is the length of the height. Area of the scalene triangle without using the height.
Aug 3, 2023 · The formulas for area and perimeter of a scalene triangle are the same as that of other triangles: Area (A) = ½ (b × h), where b=base and h=height. Perimeter (P) = a + b + c, where a, b, c are the measures of three sides.
