Question

What is the area of this triangle?

Answer 1

Answer:

0

Step-by-step explanation:

Perimeter of a triangle = sum of all sides

here, it seems that the sides of the triangle are :-

1 unit , 4 units , and 5 units

Area of a triangle = $\sqrt{s(s -a)(s-b)(s-c)}$

where,

• s = semi- perimeter of the triangle = perimeter/ 2

• a, b and c = sides of the triangle

Calculating s

s = 10/ 2

= 5

area = $\sqrt{5(5-1)(5-4)(5-5)}$

= 0 sq. units

*This means that no triangle can be formed by taking sides as 1, 4 and 5 units.

                             

Hope this helps!

Answer 2

Answer:

A=0

There is no soln for Area (A>0)

Step-by-step explanation:

take a=1, b=4 , c=5 ; a+b+c=10

Semi perimeter s= (a+ b+ c)/2

=10/2

=5

area A=Square root of s(s-a)(s-b)(s-c)

=square root of 5(5-1)(5-4)(5-5)

=0
