Calculate the area of this triangle 18cm 11cm 14cm
seraphim [82]

Answer:

  about 77 cm^2

Step-by-step explanation:

From 3 sides, the area of a triangle is conveniently calculated using Heron's formula:

  A = √(s(s -a)(s -b)(s -c))

where s is the semi-perimeter: s = (a+b+c)/2.

For the given values of a, b, c, we have ...

  s = (a+b+c)/2 = (18 +11 +14)/2 = 21.5

  A = √(21.5·3.5·10.5·7.5) = √5925.9375

  A ≈ 76.9801 . . . cm^2

The area is about 77 square centimeters.

Consider the equation 2x+1=16
Aliun [14]

Step-by-step explanation:

2x + 1 = 16

2x = 15 (subtract 1 on both sides)

x = 7.5 (divide 2 om both sides)

Since 7.5 is not an integer, (a) is No.

However 7.5 is rational, therefore (b) is Yes.
