Given,
Lengths of three sides of a triangle = 30cm , 24cm and 18cm
To find,
The length of the altitude of a triangle corresponding to the smallest side.
Solution,
We can simply solve this mathematical problem by using the following mathematical process.
Now,
Semi-perimeter of the triangle = (30+24+18)/2 = 36cm
So, the area of the triangle, will be -
= √36×(36-30)×(36-24)×(36-18) cm²
= √(36×6×12×18) cm²
= √46656 cm²
= 216 cm²
Now,
Let, the altitude of the triangle corresponding to the smallest side = x cm
Smallest side = 18 cm
In this case,
Area of the triangle = ½ × base × height = ½ × 18 × x = 9x cm²
Furthermore,
9x = 216
x = 216/9
x = 24 cm
Hence, the length of the altitude of a triangle corresponding to the smallest side is 24 cm
