Answer:

A= 57 sq units

Step-by-step explanation:

To calculate the are area of a triangle we use the Herons formula:

A=√s(s-a)(s-b)(s-c) where a, b and c are the sides of the triangle.

s=(a+b+c)/2

s=(10+13+12)/2

=17.5

A=√[17.5(17.5-10)(17.5-13)(17.5-12)]

A= 57 sq units

Maggie's brother is 3 years younger than twice her age the sum of their ages is 24. how old is Maggie?
Likurg_2 [28]

For this case, the first thing we must do is define variables.

We have then:

x: Maggie's age

y: Age of Maggie's brother

We write the system of equations that models the problem.

We have then:

y = 2x-3\\x + y = 24

We solve the system of equations.

For this, we use substitution:

x + (2x-3) = 24

From here, we clear the value of x:

3x - 3 = 24\\3x = 24 + 3\\3x = 27

x = \frac{27}{3}\\x = 9

Answer:

Maggie is 9 years old
