Using Heron's Formula we can find the area of the triangle.
A = root (s (s-a) * (s-b) * (s-c))
s = (a + b + c) / 2
Where,
s: semi-perimeter
a, b, c: sides of the triangle
Substituting values:
s = (15 + 16 + 20) / 2
s = 25.5
s = 26
The area will be:
A = root (26 * (26-15) * (26-16) * (26-20))
A = 130.9961832
A = 130 u ^ 2
Answer:
The area of triangle ABC is:
C.
130 u ^ 2
4.5 is the answer
Divide 49 from both sides
220.5 / 49 = 4.5
Answer:
NOT true:
A, C, D
Step-by-step explanation:
Let, the number = x
It would be: x + 15 = 2x - 56
2x - x = 15 + 56
x = 71
In short, Your Answer would be 71
Hope this helps!
