Question

find area of a triangle of two sides are 8 cm and 4 cm and perimeter = 32

Answer 1

Step-by-step explanation:

Solution

Let the third side be x

Perimeter= Sum of all sides of triangle

32 = 8 +4+x

32 - 12 = x

20 = x

Third side is x .

Now by using Heron's formula , we find the area of triangle

s = 32/2

=16

area=√s(s-a)(s-b)(s-c)

=32√-6cm^2

Answer 2

GIVEN :

• The perimeter of the triangle = 32Cm

• The One side of the triangle = 8Cm

• The Second Side of the triangle = 4Cm

TO FIND :

• The area of the traingle = ?

STEP – BY – STEP EXPLANATION :

NOTE :----- Let the third side be 'x'

=> Perimeter = Sum of all the three sides of a triangle.

=> 32 = 8 + 4 + x

=> 32 – 12 = x

=> 20 = x

Now, Here given sides are : 8,4,20

=> 8 + 4 < 20

=> so , here triangle will not exist and therefore, area = 0
