Find the area of an isosceles triangle, whose unequal side is 12 cm and the perimeter of triangle, is 60 cm.

Detailed Solution for Test: Application Of Heron's Formula - Question 2

Let the length of equal sides be x.$
Two sides are equal 
Then, 
x + x + 12 = 60
2x = 48
x = 24 cm
s = (a+b+c)/2
= (12+24+24)/2
60/2 
= 30
Area = [s(s-a)(s-b)(s-c)]1/2
= [30(30-12)(30-24)(30-24)]1/2
= [30(18)(6)(6)]1/2
= 36(15)1/2

The sides of a scalene triangle are in the ratio 3:5:7. If the perimeter of the triangle is 60 cm, then its area is :
Detailed Solution for Test: Application Of Heron's Formula - Question 10
Given the perimeter of a triangle is 60 cm and the sides are in a ratio of 3: 5: 7

Let the sides a, b, c of a triangle be 3x, 5x, 7x respectively

So, the perimeter = 2s = a + b + c

60 = a + b + c

60 = 3x + 5x + 7x

60 = 15x

Therefore, x = 4 m

So, the respective sides are

a = 12 m

b = 20 m

c = 28 m

Now, semi perimeter s = a+b+c/2
                      = 12+20+28/2
                      = 30 cm


By using Heron’s Formula

The area of a triangle = √s(s−a)(s−b)(s−c)
= √30 x (30−12) x (30−20) x (30−28)
= 60√3
Thus, the area of a triangle is 60√3 sq.cm
