a right triangle has a height of 20 centimeters and a base of 10 centimeters.what is the area of the triangle?

viktelen [127]

Answer:

The area of the right triangle is 100 centimeters squared.

Step-by-step explanation:

The formula for the area of a right triangle is:

$Area = \frac{a*b}{2}$

Area = (a*b) / 2

The height of a triangle is represented by a. The base is represented by b.

Knowing this, we can use what they give us for the values, by plugging them into the formula.

a is 20 cenimeters

b is 10 centimeters

Therefore :

$Area = \frac{200}{2}$

$Area = 100$

So, the area of the right triangle is 100 centimeters squared.

Ben

Step-by-step explanation:

25 goodies = 20 minutes

25/20 = 20/20

27/24 = 24/24

1.25 goodies = 1 minute

1.12 goodies = 1 minute

1.25 is bigger than 1.12.
