One side of a triangle is 10 cm longer than a second side, and the third side is 5 cm longer than the second side. The perimeter of the triangle is 60 cm.
a) Find the lengths of the three sides.
b) Find the area of the triangle.
(a)
To find:
The lengths of the three sides.
Calculation:
Given:
Let b be the length of second side of a triangle. One side is 10 cm longer than second side, so its length is
Another side is 5 cm longer than length of second side. That is length of third side is
By using the above information we can a triangle as shown below.
The perimeter of the triangle (P) = 60 cm
(b)
To find:
Find the area of the triangle.
